Not only that but it also allows to display colors outside of the sRGB (Rec. 709) gamut.

No, displays which can support colors outside of BT.709 allow this to happen. HDR processing is just a post-processing gimmick used by Hollywood to make things look even less realistic and more plastic.

Strictly speaking you are right, but in practice HDR term is used to describe both HDR and wide color gamut.

> HDR processing is just a post-processing gimmick

Can you explain how it's a gimmick?

If you are confusing HDR for the process of taking an existing Rec. 709 signal and gamut mapping into a subset of Rec. 2020, I agree that is a bit gimmicky.

This (ab)use of the technology has nothing to do with the HDR standards however, what true HDR video is, nor what material mastered for HDR is or is capable of, and shouldn't define how you see the technology (or present it to others).

You can't address the full color gamut without increased signaling bandwidth, which HDR provides. Or do you really want your 10bpp TV outputting 8bpp?
