How do we load & tweak color profiles in Fedora (without using external sensor-devices) ?
My Lenovo Thinkbook built-in screen has different (and not adjustable in BIOS) color temperature what my external DELL shows - they are quite different thus annoying.

It has been a few years since I used this. No idea if it works under Wayland, so you might have to
chose Xorg at login. Once you have acceptable profiles Wayland should use them.
Now I have two "identical" Dell monitors - P2418D - and colors are different, one has whites cooler whereas the second's whites (thus other colors) are warmer.
I've been playing with 'colormgr' but am unable to make screens to look the same.
I've also done simple "factory reset" within monitors.
Perhaps that "warmth" is something else and 'colormgr' cannot fix it - would anybody know?
Or hardware calibration - event though it's the same monitor - is the only "fix" here?
thanks, L.
