Tests consistently show a desire for higher peak brightness (even if that's achieved without increased luminance). I don't know whether anyone has actually tested for dynamic range at constant peak luminance.

TTFN,

Very interesting! So now I'm confused. Do people actually want HDR, or are they wowing 
over HDR to SDR conversion. From your presentation, including the CALM-type 
considerations, what is "the best bang for the bit" appears to me to be HDR to 
SDR conversion.

It's the same problem that plagues audio. We all want high dynamic range, but 
of we're interested in retaining our hearing, it's not practical. We're hardly 
ever in an environment that can do justice to high dynamic range, safely, with 
audio.
