You don't understand HDR. Luminance is a core component of accurately reproducing colors.

This all depends on your display. I don't know of any released displays that can do HDR justice, since MicroLED isn't out.

OLEDs can't do HDR properly, their sustained and peak nits suck because they auto dim so they don't burn out, but they can do the true low black levels.

MiniLED can do high peak nits, and sustain a high level for longer (they all still auto dim depending on how much of the screen is reaching it's peak nit range afaik). VA panels might have better contrast ratio, I haven't seen one in person. I only know of the Falcon whatever the fuck. Most good MiniLEDs are in China.

HDR True Black is not a gimmick. Contrast is incredibly important. Contrast ratio > peak nits of a display.
Independent lighting of scenes without having to drop or raise the brightness level of the entire scene allows more color variance, quality and reducing banding with lower bit depth.
Non-HDR displays fake luminance through color mixing, HDR lets you directly adjust luminance levels.
HDR as a standard enforces bit depth and color gamuts.
