Allow YCrCb420 color space to enable supported high refresh rates on some displays

I own an old 4K TV that only allows 4K60 on YCrCb420, it works on windows and on x11 just fine, however it will not work on wayland no matter what I do (be it custom edid modifications, custom mode with kscreen-doctor…). Any way I can allow that color space to be used? The fringing will not matter since I’ll be scaling up the UI, I just do not like the look of a 1080p output on a 4K display.

Thank you.
