If you have the Apple TV 4K set to 4:2:2, then you must have it set to 4K HDR 60p. You might try 4K SDR 60p 4:4:4 and, in Match Content, set “Match Dynamic Range” and Match Frame Rate” to on. So, SDR content plays back at 4:4:4 60p/24p and HDR content plays back at 4:2:2/24p. Bandwidth limits prevent HDR 4:4:4/24p compared to 4K HDR on disc. The menus are SDR and look better when set to 4K SDR. If set to 4K HDR and “Match Dynamic Range” and “Match Frame Rate” are selected, SDR/24p material will play back as such. And, if set to 4K SDR with “Match Dynamic Range” and “Match Frame Rate” on, 4K HDR/24p material will play back as such. I just prefer the latter. But, everybody likes a certain look on their own setup.
