HDR Confusion (lemy.lol)

Hey fellas, could you help me understand a bit more about HDR?

I understand that it's an absolute brightness standard, not like the relative levels in SDR
But why does it end up washing out colors unless I amplify them in kwin? Is just the brightness absolute in nits, but not the color?
Why does my screen block the brightness control in HDR mode but not contrast? And why does the contrast increase the brightness of highlights, instead of just split midtones towards brighter and darker shades?
Why is truehdr400 supposed to be better in dark rooms than peak1000 mode?
Why is my average emission capped at 270nits, that seems ridiculously low even for normal SDR screens as comparison.

Cheers 😊

My monitor (Acer XV275K P3) has a better MiniLED local dimming algorithm in HDR mode than in SDR, so even SDR content looks better that way. Also it's annoying having to switch it back and forth, it's way easier to just leave it in HDR mode and not worry about it.
