Color correction stopped work correctly

One day, i connected laptop to my monoblock (dell optiplex 7480) as external monitor and discovered that color profile suddenly switched and behaviour has also switched. My monoblock works on kubuntu 21.10 and color profile there is much better. I took icc profile from kubuntu and put into manjaro. In color correction setting I’ve selected kubuntu’s profile and rebooted. But it doesn’t change:( What i should do?


On the screenshots you can see 2 icc profiles, optiplex is external monitor (a.k.a monoblock), another is laptop.
