This whole situation is rather nasty. There was enough of consternation going from NTSC ("never-the-same-color") to digital, with the bifurcation/trifurcation of SMPTE 240M, BT.601 and BT.709, plus the bifucation of "legal" versus "PC" color ranges for all of the foregoing (thanks, Microsoft). I've seen VERY few pieces of software (and even broadcast hardware) that get even just THAT complication all sorted, and even less people who really know what they're doing operating the systems and software tools involved. Now, we're adding BT.2020, SMPTE 2084, Dolby Vision, and all sorts of proprietary stuff like Sony S-LAB. This is going to be a disaster -- nothing will properly talk to each other, e.g. cameras, encoders, video displays/monitors. Everyone can't even agree whether 10-bit is enough or whether we really need 12-bit for accurate reproduction. SMPTE and ISO just punted the question down the road by saying you can have any flavor of ice cream you want. I predict fun times ahead at next year's NAB...
