Yes sir, did think about these. With so much of content to read and specs to worry about - we at times over estimate our needs may be. My current Sony TV got 400nits of brightness and I had never an issue with its brightness levels. It was set at 60% years ago and still running at that.
So I feel comfortable that 550 nits will cut me in. I don't have lot of confidence in H8G in India as yet. Hisense supplies panels to VU and while they are good, I am not willing to go that way for a TV which lasts 6-7yrs for me. So, even if I get the super bright 1200nits from 950G, I may run it with 30% brightness
Viewing angle does seem concerning. I read in this spec sheet that 50in and lower don't have wide viewing angle, bit higher ones do. Attaching the spec sheet.
Also, very few online video reviews exist. One from Michael Fisher of Mr Mobile shot the TV from multiple angles and I found them good enough. These are still not conclusive I believe. Hoping to see this TV in person before making a judgement.

Head over to Rtings. They have the viewing angle on a video. You can play the video to see the gradual change, and also, switch between the two by pausing and see the difference.
Moreover, viewing off-axis makes blooming and zone changes more apparent. So H8G will be good, if you sit in front and watch. In my case, dad usually sits way off axis. Thankfully with OLED now, he still gets a fantastic picture.
The high brightness isn't for SDR content. It's needed for HDR content. Like I have mentioned multiple times and in my magic of OLEDs thread too, more often than not, it's small areas that need to pumped to high levels of brightness, and pumping small areas to max is the one thing FALDs stutter with. Even at 2% that Rtings measures, you'll see a drop in measurements. 2% is still a big area. Make it 0.5%, and it'll be either another big dip or blooming. Samsung dips the brightness and crushes blacks; Sony and Hisense too seem let blooming happen and not crush blacks.
Flatpanelshd measures 1%, and guess what, Q70R, that can touch 800 nits on a 10% window, measured only 200 nits on 1%. That's not HDR territory. This is the reason you'll see OLEDs being the best TV pick, especially for HDR, by Flatpanelshd, Rtings and more.

I find them to be the most thorough. They also highlighted Samsung's wide angle filter smudging details a bit, which is something harshly anyone else noticed.
