HDR has problems that aren't the fault of missing color management. Notably, the fact that HDR of the HLG & PQ variety (so HDR10) do not have specified behavior. The specs are wrong in that they basically just don't exist for half the problem. Which also means most content is badly authored, too, almost certainly including your fancy pants Nikon. This is why gainmap images almost immediately dominated the mobile phone capture space, they are actually properly defined. So both viewers and creators know what they're actually intended to do. The rest of your rant seems mostly anchored around the fact that most things still produce sRGB, which is true, but they still typically map inputs into sRGB appropriately (that is, they get clipped). Which still is being properly color managed.

All of my rant applies identically to 10 bpc images and wide gamut (non-sRGB) for exactly the same underlying reasons. They all have the same fix: frame buffers must be 16 bpc and input images must be color managed. HDR has one extra minor issue on top, which is that there needs to be an output mapping to the display max brightness capabilities but this isn’t that different to what’s needed to correctly tone map wide gamut to arbitrary displays. Also: if the spec is so “wrong” why does YouTube HDR just work? Also… Apple TV, NetFlix, etc… on practically all devices? They got it right! There is no fundamental color management difference between moving and still images. If anything, moving images are harder!
