So....even with an excellent display transform, which gets you some of the way there to the final look with a *flick of a switch*, so to speak,

in order to produce an optimized Rec.709 (color) version of a feature motion picture, it has been the custom for high end post facilities to dedicate more time/effort (roughly average booking time ~2 days for high end movies, but that varies depending on the technician and the filmmaker/production) in order to fine tune with what’s called a ‘trim pass’ of the original (P3) grade.
