Anyone was able to successfully play 4K Dolby vision content with this TV via HDMI? (Via Apple tv or shield)

All the encodings work for me over optical cable (I believe the DD+ mode just sends 640 Kbps instead of usual 448 though since full DD+ can't be sent over optical). Don't have an ARC port to test this, but could be an issue with the cable as well. Not all HDMI cables support full ARC bandwidth.
You can get DV on the TV, just need to pass 4k 30 or below.
You are over-exaggerating an issue that doesn't exist. Any SD content is not going to look like UHD HDR content with upscaling. Even the best TVs are only able to improve PQ on poor content by about a bit. I use MadVR for upscale which is better than any TV and even on that 720p content looks poor.
Your old Sony looks better because it's smaller and issues aren't as apparent. On a bigger set, there will be more visible imperfections. My 42" Sony which I got for ~70k in 2013(very expensive adjusted for inflation) also looks better on SD content because it's smaller. However, if I sit a proportional distance according to screen size, it looks worse than the U79 in terms of upscaling.
The upscaling is fine on this TV for a TV set. It's more on the softer side but there are no artefacts. You can add edge-enhancement if you want a sharper picture by adjusting the sharpness setting. On a 55"+ TV, SD content will look poor regardless.
You should look more into what looks poor to you and try different settings. Maybe it's a configuration issue and not really an issue with upscaling in general.
He's exaggerating it a lot. Folks generally have very high expectation from upscaling on a TV with really weak SoCs. I don't know why that is, but unless you're using something like a high-end HTPC with MadVR or using a non-real-time upscaler (like Waifu2X or Topaz gigapixel) you are going to get very small gains from that. I've seen even 2+ lac TVs attempt and fail to get good PQ on low-quality content. You can't magically create detail that isn't there in the source content.
This has been discussed and addressed before in this thread. The issue is that this TV can only accept up to HDR10 if you pass a 4k 60Hz signal to it. You will need to pass a 4k 30 signal to it to get DV working. If your streaming device supports matching content framerate, that will automatically pass a 4k 24 or 30 fps content to the TV and you will get Dolby Vision working. I've been able to verify that by forcing 4k 30 and 4k 24 out of firestick 4k. The auto framerate matching function is buggy right now, but when it gets fixed, I'll switch to that.
I've also verified that the new iPhone 12's Dolby Vision format (HLG with DV metadata instead of HDR10 with DV metadata) works on this TV. And native player for this TV can play 4k 60 DV fine.
--------------------------------------------------------------------------------------------------------
Now the main purpose of why I came back from the dead: This is because after watching a lot of content, I thought that there should be another mode for low-quality content we frequently watch, like a 1080p movie over Hotstar or DTH content. That content is not mastered very well and in dark scenes, there was a very high green cast on my TV.
If it's also visible on your set, you can set the white balance in expert settings to Red -2, green -6, blue -2. These will crush the dark scenes to black, which also do help with a lot of low-luminance noise which is present in low-quality content since it's also likely shot with worse cameras. These kind of scenes are best for tuning the white balance since the human eye can very easily see the white balance wrong-ness in those areas.
This is not an issue with most of the SDR 4k content or any of the HDR content, but even for those I found a bit of green cast, so I set it to Red 0, green -2 and blue -1.
I'll come back in case I find something else new. Hope these help in the meanwhile
I saw the Toshiba U5050 55" in one of the reliance digital showrooms today.
It was absolutely sad and pathetic.
I dont know what is all the hype about.
Please do NOT buy this tv if you are not able to demo it prior assuming U7980 reviews here.

Unlike U50, the U79 is a reviewed model overseas as the Hisense H8F. You can get countless reviews by professionals, which is much better than watching SD Saas Bahu serials in a poorly lit showroom with awful settings. Even the LG 77" OLED looked quite bland in the showroom to me due to poor content and lighting, while I know how good even a B8 can look at my friend's place in a dark room with good content.
This is why I was able to take the plunge on this v/s the U50. I don't trust Indian YouTube TV reviewers at all, because they even praise garbage TVs from TCL or OnePlus.

Did we conclude that issue is on the TV hardware side or was it Fire stick limitation?

Both sides have issue right now. Firestick currently has some software bugs which make the auto framerate mode not work and it always sends a 60Hz signal. This I expect to be resolved. When it gets resolved, it will automatically send a 4k 24 or 4k 30 signal on DV content and that would work. Currently you can force a 4k 24/30 signal always but that results in bad pacing on 4k 30/24 content and 4k 60 YouTube videos.
The TV side issue on the other hand should be a firmware one. It should technically be fixable as 4:2:0 4k 60 DV should be able to be passed over HDMI 2.0b. However, I'm not very sure about that as it might be an HDMI one as well. This side I'm not confident will get solved as Toshiba's software skills seem underwhelming to me and there's no forum to submit bugs.
Overall, the best hope to get DV content right now is either for Amazon to fix the firestick bugs or for VIDAA 4.0 to come with better apps. The TV's inbuilt Netflix app is already pretty good and I use that for DV content. If the Plex, prime and Disney + Hotstar apps also become good, you'll not need firestick for much anymore. As I said, I don't expect the TV side 4k 60 DV to get fixed.

@lightgamer : How do you play large BR rips over the network? I usually do this via USB but was exploring DLNA vs Plex? Which do you suggest? Which of these 2 transcodes the Video on my workstation and which allows the TV to do it?
The files ill be playing are around 50GB/movie.

I use Plex for it. DLNA is more like file sharing while Plex is an entire experience with a well-defined structure, recommendations, having a watch list, ratings, episode summaries, album art and so on... IMO, there's no comparison. Plex is fantastic and there is no equal to it.
Regarding transcoding, it's a complex topic. Plex will transcode when it finds unable to render something as expected. For example, if there are '.ASS' subtitles which have their fancy font rendering, Plex will use your workstation to transcode that video and burn the subtitles in. You can turn on or off that behaviour for these subtitles and render them plain which will result in direct play. Plex will also transcode audio if your TV for example can't play a certain audio or video file. You can set it all in settings. There are still some features getting worked on but it's by far the best experience for local network playback.
Most of my rips are around 25-40GB in size since they are encoded in HEVC. They play just fine on this TV over plex without any transcode required. Transcode is generally required when the compression is very high or with weird subtitles. I generally avoid transcode since this TV can decode most formats, but it can do it if you want it to.

What's the source for finding BR Rip? Could you share over PM if this thread is not appropriate?

I will chk the cable I am using for ARC but I remember that its a good cable I got from MiVi. Will recheck on this and shall revertAll the encodings work for me over optical cable (I believe the DD+ mode just sends 640 Kbps instead of usual 448 though since full DD+ can't be sent over optical). Don't have an ARC port to test this, but could be an issue with the cable as well. Not all HDMI cables support full ARC bandwidth.

Thanx man.
I was actually trying this on my C9 and my Plex app is unable to find my server. Ill try posting it in the C9 thread and see what comes of it.

The Plex app doesn't work on my U79 as well and it fails to find the server. I believe it's the same reason for both of us.
I believe the reason is that the Plex app is outdated on both VIDAA and WebOS. This was the main reason I got a firestick 4k (and I recommend you do too before the sale is gone). The Plex app is also a lot newer and works better on firestick than on VIDAA.
