Can you also see that in screenshots (when viewed in SDR mode), and/or when zooming in a lot on the desktop? I suspect that this could be the display doing some processing to make the image "better".
If you by "zoom in" mean kwin zoom (Meta + scroll), the effect essentially disappears after zooming in a few times (on the HDR monitor) Aaaaaand I just checked, I have "super sharpness" turned on in my monitor settings, turning it off removes the dots... but also makes everything a bit blurry, so I guess this is not a KDE bug after all :/
Okay, then we can close this.

I could at least tune it to not visibly change the image a lot, but you really shouldn't have to... Displays are so annoying!
