How much of the colour change is also dependent on the film printer and also film scanner/telecine?
It just seems like there’s a lot of variability in each step to end up with an unintended colour, that will taken as the artist’s intent.
Any digitizing is done before color grading.
All steps before try to not affect the color and keep as much dynamic range as possible to give as much leeway as possible for the colorist.
Realistically, for Pixar and Disney (not people with limitwd funds, say), the color grade is much much more relevant to the final color than the specifics of digitizing.
