I have been doing A/B Testing between Xbox One S and Apple TV 4K (2nd Gen)I think I have already answered your question but happy to restate
Subjectively
ATV+ looks subjectively the same
Netflix used to look worse with artefacts in dark /busy scenes but comes pretty darned close now
Hotstar was noticeably worse but the recent releases (Disney) have got quite good
Lionsgate, I have watched only 1 TV series so cannot really say
I don’t use any other OTT service
Technically:
- Typical BD UHD movies comes in a 2 disk set of which 1 is normally a BD66 containing the UHD movie and a BD 50 for the 1080p + extras
- This 66GB disk is around 80% video content encoded in h.264 for a 2:30 movie, let’s take 2:15
- That yields an average bit rate of 53.5mbps (66*1024*0.8*8)/(3600*2.25) in h.264 encode
- This is very roughly equivalent to an average bit rate of 26.75 mbps for h.265 -
The compression efficiency of h.264 vs h.265 can vary though depending on content so I’ll err on the conservative side and use 40% instead of the more widely agreed 50% so that we don’t end up chasing a red herring - so thats 32.1mbps
(and let’s please not get sidetracked on this - neither BR nor OTT use lossless , and h.265 is a significant improvement over h.264)
In other words, a 26-32mbps average bitstream on OTT should yield a PQ technically equal to a commercially available UHD BR
Some OTT providers meet or exceed that already, others are close and should improve in the very near future
so there you have it
I have the following observations (very perceptible in my set up) so far
1. The sound quality on Netflix and ATV+ is much better using Xbox One S. The dialogues are much clearer and crisp, the LFE has more impact and details, the Atmos Channels are efficiently louder. If SQ on Apple TV 4K is 7/10 than Xbox One S is 9/10
2. On my Projector, I did not notice and difference in picture quality between Apple TV 4K and Xbox One S
3. Atmos umpiring on Xbox One S is super amazing, still to try on Apple TV 4K
4. With Media Remote, using Xbox is as convenient as using Apple TV
To all FMs, please note that I am not challenging anyone's observation or experience, I am only conveying my own personal experience.
