Is there a tool to adjust gamma on KDE Wayland similar to kgamma on X11?
This is about brightness-colorcorrection not actual backlight control.
kgamma only allowed this for all displays at once (settings per display were non functional). That would be ok, but control per display or maybe ever per application would be even better.
I know nothing about this subject but does anything here help - Kde wayland for artists - KDE UserBase Wiki

I found a solution.
I loaded some icc color profiles from here.
Then i can go to the display configuration and load the profile with the desired gamma value,
It’s not perfect, but allows to set values per display and with proper naming for the profile-files is not much of a hassle either.
