Color Calibration in KDE

In xfce there are already a preset profiles. I do some 3d rendering and maybe I am just lucky with my monitor and printer because I print my stuffs almost identical to my drawings as shown on my monitor.
When there is a difference I just eyeball it manually like during my old days working as architectural delineator by hand . Anyway this is just now a hobby. I’m already retired.

DisplayCAL I think needs the

colorhug

for the colorimeter. It is present in tumbleweed, it might be in Leap 15.3 also.
