Correct me if I'm wrong, but isn't the color operation done with a logC to rec709 a 1D lut?

Any visible color, as in the entire gamut of the human eye?  We're a long way off from that, I'm afraid.  Projectors are still making images by shining red, green, and blue light up there, so that's a major constraint.  But you'd think they'd be able show everything we can see on a computer monitor at least.  Maybe they can.

Ironically, part of the forthcoming IIC/ACES standard is the "Reference Rendering Transform", which is like a standardized film look.  And like other film looks, you can't get fully-saturated colors.  Similarly, I worked on the most recent "A Christmas Carol" which is a completely digital film (including projection), and yet we still created a film look for it.  Somebody thinks that people still like that film look.  But I assume with digital projection you can opt out if you want.
