I have issue with my ICC profiles not loading properly using KDE Wayland monitor inbuilt feature in display configuration. It makes my screens way too dark and I know that’s not how it’s suppose to be because I color calibrated my monitors and it was loading them perfectly fine on x11 using xcalib and in windows 10. I’m running Arch Linux with latest 555 Nvidia driver.
Please make a bug report for KWin, and attach the ICC profile in question there
