Meaning that with lower brightness, it looks fine? If that's the case, then I
think that's just the display clipping rgb colors in an unfortunate way, and
you just have to keep brightness a bit lower

When I set the Max SDR Brightness slider to 355 and the Brightness slider to
100%, previously white colors shift toward yellow.
This occurs on both HDMI and DisplayPort connections

The display is factory-calibrated by the manufacturer, and I'm using certified
cables—both a VESA-approved DisplayPort cable and an HDMI-certified cable.

That's odd, not sure where such a tint could come from though. Perhaps the
display simply selects different settings / color balance depending on the
input?

Now I finally understand what you meant about the brightness control in the KDE
UI.
However, the display still has a yellow tint when connected via HDMI.
It was misleading because it seemed to work correctly on HDMI outputs, but on
DisplayPort (DP), it was too dark by default.

Thank you for your response. While I'm not yet familiar with the KDE codebase
and Linux codebase (DRM, drivers), I'm eager to help troubleshoot and debug
this issue. Please let me know how I can contribute to resolving it

Intel GPU via DisplayPort (DP) in HDR Mode:
It does not work properly when connected via DisplayPort in HDR mode. This is
not related to the monitor's brightness settings.
It  works fine over HDMI, but there is a noticeable yellow tint in scenes that
should display white.

For AMD it seems the same issue as mine 
"It's like a green-tinted overlay..."

Please describe exactly what's wrong, and what issue is happening with which
GPU.

Afaict though, the first one is fine (you just have brightness at 0%), and the
second one is https://gitlab.freedesktop.org/drm/amd/-/issues/3358 ?
