I thought I read somewhere (or maybe not!) that a very specialized display was
available to do that. Maybe in scientific circles; can't remember where I saw
it. Perhaps just wishful thinking!
I've been wondering about the latest whiz-bang flat panel monitors, with their
supposed 10-gazillion-to-1 contrast ratios: whether or not that would suffice to
show HDR images raw. But I suppose the internal circuitry still works in the
standard 8-bit-per-channel way. Not to mention the extreme brightness levels
that would be required of the pixels as well.

Fascinating! I've never seen it explained that way. More research to do!
