I love HDR for movies/shows on OLED but other than that I agree. It really sucks you can't disable HDR in apps like Netflix etc. It does look terrible on non OLED TVs. In Chrome you can force a specific color profile in the settings. I believe sRGB shouldn't allow HDR content.

Personally I think the biggest benefit of HDR is not even those super bright annoying colors but 10-12 bit colors and the fact that we can finally have dark content. If you look at movies from 10-20 years ago everything is so damn bright.
