Real-world support for full range and greater color depths

[benwaggoner]

I am doing some playing around with 0-255 luma range and 10-bit encoding.

I was wondering how good real-world player support is for those modes. I know that there are certaninly good software players for those. But how about GPU accelerated playback? Or ASIC-based playing in living room and handheld devices?

I imagine 0-255 is more broadly supported, since it's part of the original profiles. I know there's been plenty of talk about 10-bit support in ASICs, but I'm not sure if those are in the wild yet, or if the devices's media software will support correct playback of those if provided with files in Hi10P. Let alone Hi422P or Hi444PP.

So, can anyone offer any tips for what players and devices are or are not known to work? I'd love to be able to see what kind of quality differences I can get outside of computer monitors.
