Thanks. I can think about some of these topics but I can’t use hyprland because there is no color management in Wayland :\
For ICC profiles colormgr can help: https://wiki.archlinux.org/title/ICC_profiles#Wayland
If you just need basic brightness, contrast and gamma, wl-gammactl should do that: https://github.com/mischw/wl-gammactl
BTW Hyprland is not required, it's just the most practical way to have shortcuts key mappings in Wayland
