Of course, I'm making the assumption that any push by manufacturers to a
larger colorspace would take *years* and by then the displays would
generally be 10bit+.

I don't think it's far fetched at all to assume that if/when we see another
standard space, if it isn't just "XYZ and good luck" like DCI, then it will
be a larger space and it will assume higher bit depth displays, and 709
would obviously be a key "legacy" emulation target.

Best I can find is a verification that the iPad 3, yes, wow, displays
actual 8 bit color! :)
