DisplayCal offers the option to apply the created profile directly:
https://wiki.archlinux.org/title/ICC_profiles#xiccd
I need to see how i can apply noto second display:
Metadata: MAPPING_device_id=xrandr-AOC-27B2F1G5-VAFNBHA005533
It shows for the one it applies but second one (same device) seems not to be added..

easy π
