I'm not sure what's messy about it? Besides DisplayHDR400 allowing 8-bit colour processing despite pretty much every HDR standard using a 10-bit base anyway, it's a fairly uniform set of sub-standards varying only in maximum brightness & now minimum brightness really(While B-W does change for True Black that's more to do with the panels they expect it on rather than a perceivable requirement).

Adding the True Black option helps non-technical users understand that good HDR isn't just about maximum luminance and that OLED screens and the like can still provide excellent HDR experiences in spite of their traditionally lower brightness, just for different use cases.

For the most part, DisplayHDR500 now basically means "Any HDR protocol should work on this", which is kinda useful now we have a sea of various HDR protocols, with some getting patched into hardware at later dates via OTA updates.

It is not messy for you and me. But how would my mother buy HDR TV?

So do you have a standard system in mind which would both work for the technologically illiterate people and also be meaningful for those who know their stuff?

I'm glad these vesa standards exist since labeling every TV HDR because they support 10bit input is deceptive marketing.

If your mother had to buy a HDR TV pre-DisplayHDR, then you'd either have to:
1. Let her rely purely on marketing material
2. Tell her to dig deep into each TVs specifications for a collection of parameters & protocols that might not me prominent, if they're listed at all, and give her an understanding of how to judge those specifications.

Now, you can just say "Make sure it's DisplayHDR certified, the higher the number the brighter, some can also go very dark". Is that not a lot easier?

Sure, DisplayHDR technically doesn't specify *which* HDR protocols a display supports, but given it's a paid-for certification process you'd assume any genuinely HDR display would at least support the open standard used by most media, HDR10(And I doubt any display with at least DisplayHDR500 will ever release without that support).
