"Color Corrections" entry missing in "System Settings"

[Riusma]

The entry "Color Corrections" is missing in plasma "System Settings" (I think it is since Kubuntu 20.04 at least, I only use LTS versions of Kubuntu).

I suspect that is it due this abandoned bug (https://bugs.kde.org/show_bug.cgi?id=433068) and the fact that it is not possible to operate color calibration ("You need Gnome Color Management installed in order to calibrate device") which is one of the functionality that was linked to this entry.

Please note that the "Color Corrections" entry also provide an easy graphical interface to users that want to install ICC color profile to their monitors (and check if an ICC color profile is correctly associated to one monitor). While not "vital" for graphists or artists (I didn't reported the "missing feature" when it appears for me in 20.04, shame on me) as I trusted the software DispayCal (now more or less abandoned and only available as a Flatpack package... being an graphists / artists on linux is more and more difficult) to properly apply its profile after each calibration, it allowed nonetheless for an easy switch between ICC color profiles applied to monitors and an easy way to check if "everything is in place". :)

1/ Is there a way for me as an user to add this entry manually?
2/ If not, would it be possible to bring back the entry as an option?
3/ Maybe it is possible to "just remove" the part that is linked to the "Gnome Color Management" and keep the entry in System Settings"?

I understand that graphists and artists that use and need ICC color profiles attached to their monitors are a very tiny niche community but that functionality was nice! :)

PS: not sure what is the status of this entry in Ubuntu Studio (which is using Plasma now?). :|

PS2: ok, sudo apt install colord-kde allow the installation of the missing "Color Corrections" entry... it seems to have some weird interaction with ICC profiles stored and installed with the DisplayCal flatpack as selecting any ICC profile don't seems to do anything (I will try to copy the ICC profiles generated by DispayCal outside the flatpack repository and not use DisplayCal to apply ICC profiles). :)
