Wayland 4K@120Hz over HDMI - how to change color scheme

Hi,

I know that basically there is no GUI for settings. Is it possible to change color scheme from RGB to ycbcr420 at least from command line? In Windows, I can get 4K@120Hz over HDMI, because drivers shows color scheme ycbcr420. In Linux, only I get only 60Hz. All topics I found are for X11, which I can’t and don’t want to use.
