I do wonder how long it will take to discard all that quality damaging baggage from the video standards developed for the analog-converted-to-digital days. That all standard UHD still uses 4:2:0 video level encoding is pretty sad really.
Even YouTube and Netflix et al. are encoding in YUV 4:2:0 video levels.
Probably because the video decoding side has traditionally also been really poorly supported on computers. Until hardware decode became standard (very recently) no one payed attention to how to do things correctly. GPU drivers still cannot get basic standards correct all the time. This means there would have been terrible issues for a lot of people for a while after any change, so no one was ever willing to change.
Edit: bandwidth costs money, even only in-device bandwidth... probably the real reason 4:2:0 is still standard.
AV1 should take the opportunity to go pure full-range 4:4:4, but they won't.
