That's not inherent to HDR though. BFV (unless I'm confusing it with something else) has a HDR adjustment routine where you push a slider until the HDR white and the SDR white are identical. Same could be done for desktop environments. In my experience, HDR support is very lacking in PCs atm. You can't even play Dolby Vision on Windows, which is the only widely-used HDR format with dynamic metadata.
If you mean https://i.imgur.com/0LtYuDZ.jpeg that is probably the slider GP wants but it's not about matching HDR white to SDR white, it's just about clamping the peak HDR brightness in its own consideration. The white on the left is the HDR brightness according to a certain value in nits set via the bottom slider. The white on the right is the maximally bright HDR signal. The goal of adjusting the slider is to find how bright of an HDR white your display can actually produce, which is the lowest slider value at which the two whites appear identical to a viewer.
Some games also have a separate slider https://i.imgur.com/wenBfZY.png for adjusting "paper white", which is the HDR white one might normally associate with matching to SDR reference white (100 nits when in a dark room according to the SDR TV color standards, higher in other situations or standards). Extra note: the peak brightness slider in this game (Red Dead Redemption 2) is the same knob as the brightness slider in the above Battlefield V screenshot)
Thanks for clarifying this!

I think it's because no one wants it.
No; Windows 10 barely supports it, and of my hundreds of Steam games, exactly none have any code making use of it; seemingly only AAA mega-budget games have the pipeline bandwidth, but e.g. Dune Imperium and Spaceways have no reason to use it and so don’t bother. Windows 11 focused on improving wide color support which is much more critical, as any game shipping for Mac/Win already has dealt with that aspect of the pipeline and has drabified their game for the pre-Win11 ICC nightmares. Even games like Elite Dangerous, which would be a top candidate for both HDR and wide color, don’t handle this yet; their pipeline is years old and I don’t envy them the work of trying to update it, given how they’re overlaying the in-game UI in the midst of their pipeline.
(It doesn’t help that Windows only allows HDR to be defined in EDID and monitor INF files, and that PC monitors start shutting off calibration features when HDR is enabled because their chipsets can’t keep up — just as most modern Sony televisions can’t do both Dolby Vision and VRR because that requires too much processing power for their design budget.)
It's an absolute mess on Windows. It's one area where I totally bow to Apple's vertical integration which makes this stuff flawless.
Nothing you're written disproves that no one wants it, if anything the fact that nothing really supports it implies that it's not a valuable feature that people are clamoring for.

I want it. And, I'm hardpressed to imagine a multimedia consumer that doesn't care about color and brightness ranges, unless they don't understand what that is. Every movie is recorded and many phones now capture in a range that can't be encoded in 8-bits.
