What I would like to see in the PS5 and PS4.5 (being a UHD blu ray player)

Also make sure it's HDR ready since that's also supported on UHD blu ray. As for 4:2:0, the UHD blu ray players themselves are upgrading the footage towards 4:4:4 or at least the samsung and Panasonic are going to do that. Although I must say I am not hapy about the fact that a player needs to do such a thing, oh well software updates might fix that one. As for the theorie, it could work, but why they not make sure it 3840x2160 4:4:4 (colour and luminance/grayscale) is truely beyond me.

HDMI2.0 does support 4:2:0 though only at 50/60 frames per second (FPS). At 24 FPS 10 bit only 4:4:4 and RGB are supported.

Hence the player has to do the conversion.
