The page I linked points out that using the settings is an alternative, to double clicking ICM file from file explorer.
You could also try more manual way, by following the Arch linux wiki guide: wiki.archlinux.org/index.php/ICC_p...
It should apply to your system as well, as under the hood both systems use xorg graphical stack.
Have you tried importing ICM by itself?

I have choices and I can see, as can be seen in the upmost screenshot.
However, I cannot truly tilt color settings to my preferences.
I also have installed DisplayCAL; but I cannot figure how it works at all.
