As assured, it seems the feature is now rolling out gradually to all users. As pointed out previously, the videos are being served in VP9, which indicates its most likely either tvOS or the YouTube gamer for Apple television is decoding the codec in software application. This is, obviously, not minor, especially at this resolution, which is likely why only 30fps videos seem to be playing in 4K while 60fps videos appear to be playing up to 1440p. And there is no HDR, which would need additional processing. Lets not forget, the Apple television 4K is working on a three-year old A10X, which is based upon a four-year old A10.
Message on Apples website.
From screenshots submitted by these users, 24/30fps videos appear to be available in complete 4K. When Apple Television 4K was very first launched 3 years back, it supported 4K HDR playback of most services with the noteworthy exception of YouTube. This is, of course, not trivial, especially at this resolution, which is most likely why only 30fps videos seem to be playing in 4K while 60fps videos seem to be playing up to 1440p. Lets not forget, the Apple Television 4K is running on a three-year old A10X, which is based on a four-year old A10.

From screenshots submitted by these users, 24/30fps videos seem to be offered in full 4K. It seems 60fps videos only appear to be available up to 1440p. According to the YouTube statistics, all of these videos are playing in Googles VP9 codec.
Due to this issue, Apple television 4K users were left bereft of 4K YouTube for 3 years. That was till earlier this year, when Apple revealed that 4K YouTube would be concerning the Apple TV 4K in tvOS 14.
When Apple television 4K was very first launched three years ago, it supported 4K HDR playback of a lot of services with the significant exception of YouTube. This was due to the reality that YouTube uses Googles VP9 codec for all videos above 1080p resolution and the gadget would require either hardware or software application decoding to play it back. Hardware decoding of VP9 is not readily available on Apple silicon and the YouTube app does not perform software decoding.
Considering that Apple never ever really assured HDR, its likely that will not be coming to the YouTube gamer on Apple television 4K. Likewise, we cant yet totally make certain if the limitations with resolution and frame rate are because of the minimal processing power or simply peculiarities of the initial present.
