> HDR is only meant to make a handful of elements brighter -- glowing lightsabers, glints of sunlight, explosions. HDR is never meant to make any of the content darker.
I have to do some math to check if this matters or not, but HDR is able to make dark scenes much better too. SDR video doesn't have nearly enough bit depth to represent anything dark well (it's not even 8-bit) whereas 10bit HDR does. So I would expect to see more dark scenes in properly displayed HDR.
Also, in dynamic HDR you should be able to make a dark scene by encoding it brighter and using the metadata to darken it, though I don't remember if it actually works in practice or if anything does it.
