Plasma 6 Wayland with colord-kde v24.01.95

SUMMARY
kcm_colord KDE Plasma 6 Wayland doesn't show any display device.
On KDE Plasma 5 Wayland and KDE Plasma 6 X11 display device is listed

STEPS TO REPRODUCE
1. Open "System Settings" > "Connected Devices" > "Color Management"
or launch "kcmshell6 kcm_colord"
2. On the Devices tab search for Display device on the list

OBSERVED RESULT
No Display devices

EXPECTED RESULT
Even on VM there should be display device

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Kinoite 40 (Rawhide)
KDE Plasma Version:  5.93.0
KDE Frameworks Version:  5.249.0
Qt Version: 6.6.1

ADDITIONAL INFORMATION
1. Both KDE Neon User (Plasma 5) and Testing (Plasma 6) editions provide colord-kde v23.08.4, and there I see the same issue. So I don't think that it's a regression with QT6 port (version 24.01.90+), distro packaging issue etc.
2. ICC profile assignment with "System Settings" > "Input & Output" > "Display & Monitor" > "Display Configuration" works properly on KDE Plasma 6 Wayland.
3. On KDE Plasma 6 Wayland, printer appear in the list.

This is expected. colord is not used/relevant on Wayland (except for printers)
