[gnome] [wayland] [nvidia] 10bit color problem

hello, pretty long ago i stuck with problem and want to fix it. my monitor supports 10bit color, it works in x11 session(but without hdr, as i know hdr isnt supported in x11), but doesen`t in wayland. hdr image is supported and works well, but without 10bit color. modetest -c shows that:

101 Colorspace:
		flags: enum
		enums: Default=0 BT2020_RGB=9 BT2020_YCC=10
		value: 9 

as i know, it means that my setup supports 10 bit hdr color.
how to force color palette to 10 bit? theres any way to use 10 bit with hdr(and if its possible on x11)? maybe i should try some other de/wm?
using: gtx 1080 ti with last non-opensource dkms drivers(nvidia-dkms 580), AOC Q27G4X(which 8bit+frc), connected via displayport; also using gnome 49.3, linux_zen (6.18.7-zen1-1-zen)
