The catch is probably in that “standard illumination”/“standard light”. A lot of photographers rarely use standard light, or use it in combination with non-standard light.
And if the lighting is not standard, correcting the skin colours only could look strange (I find that often the case with portraits taken during sunset with a fill flash).
Extreme exemple: a model on grass under a tree, for extra fun have him/her wear a bright red shirt; you expect the skin colour to be “non-standard” and to vary…
Also, film makers have to be able to combine shots from different days, making colour control much more important. And they have fairly standardised viewing conditions for their products, and much more specialised personnel: lighting, video, editors, etc.
