Wait... Isn't pure white the same intensity in any case? Why doesn't it all scale? Any docs on this?
That's what HDR fundamentally is - you're not restricted to the constant standard range, but have a high dynamic range. Values can go above "pure white".
Makes no sense to me.
I always understood HDR as having more subdivisions between 0 and 100.
Why would anyone design a phone screen that won't go to 100% brightness with SDR?
Sustained brightness over the whole screen and peak brightness over a smaller portion of the screen usually aren’t the same. And most phones indeed ignore the set display brightness in order to display the hdr content as accurately as possible. Which does make sense to some extent but can be annoying.
