Disclaimer:  I'm in a live environment. Using KDE Neon Unstable ISO(12/02/2024).

When I apply night color on my laptop, it only affects the laptop screen, not the external monitor attached to it. I should mention that this can't be a case of hardware issue as I use Plasma 5.27 on the same setup and Night color is applied to both. 

STEPS TO REPRODUCE
1. Apply Night color via any method(Always On or Time bsaed)
2. 
3. 

OBSERVED RESULT
Night Color only applies to laptop screen.

EXPECTED RESULT
Both screens should be affected.
