On the Adobe Support Community Beta Page, we can see the new Lumetri Color Settings Tab (Hurrah).
We now have Input Color Space, Working Color Space and Display Color Space. Still kind of wish it had an ouput color space like in DaVinci Resolve, but will have to see how it works.
Still nothing like Rec 709A to deal with the Apple Color Shift issue though, and it doesn’t sound like they will touch on that.
