Another thing to remember is that current cameras can capture upwards of 14 stops of dynamic range, that's over 10,000:1 (16384:1), but digital cinema is only capable of 2,000:1. HDR, as described in the above Dolby white paper is more of a way of mastering content to work on displays with a wide range of dynamic range capabilities. So why wouldn't it be the case that a JVC, with 350,000:1 dynamic range capability, couldn't use the HDR Metadata to reproduce the image differently (better) than a standard, 2000:1 DLP projector? And given that information was baked into the master, by the content creator, isn't that a more accurate way to do it?
DCI requires a minimum of 2000:1 on/off CR. The Sony's and newer Barcos capable of much greater, but house safety lighting is the limiting factor for dynamic range in exhibitor theaters - unless you want to operate at higher average light levels.
I'm refering to projectors (watching movies), not TV displays. You watch movies in a darkened room, and a 1000 nit bright area in the image would to "hurt" your eyes if you are watching at the current SMPTE recommented standard.
Now sure, you can leave everything the same, and have glints off of cars, and light bulbs show up at 1000 nits in a theater, and it's going to look like someone on the screen is shining a flashlight at you.
Now for watching sports - you may want brighter - but most sports are well lit, or are outside, and do not have a large dynamic range.
I'm all for recording masters with as much fidelity as possible to ensure everyting is captured. This is no different than with movies captured on film negatives, which have much more exposure latitude than the movie print.
Regarding the JVC, won't the (UHD-BD 2.4 gamma) 10 bit video (and potentially later 12 bit) increase the dynamic range of the recordings?
With the new UHD-BD there are some things I'm really looking forward to, like higher bit depth for color. Next is wider color gamut, although, I'm not sure it its going to matter much, time will tell.
As for HDR, I don't see the need (for projectors), but I could be wrong on that too. Just my 2 cents.
