A lot of even high end pros don't have the faintest idea about colour. I have seen pros, real household names, wax lyrical about this lighting setup or that lighting setup because of a colour cast, yet not having a clue about camera profiling. It is kind of embarrassing the misinformed uneducated rubbish they come out with sometimes, particularly about colour, but hey, they are much better image makers and promoters than me!
Many don't do anything, they leave all that to "the retouchers", some use grey cards but believe WB is all that is needed for good consistent work while some, depressingly few, use colour cards and make profiles. It is funny, they know what light they like, they can tell you what time of day an image was made in their daylight studio from the colour on their calibrated monitor, but they couldn't tell you how to create exactly the same look with studio lights, or visa versa.
As far as lighting goes, junior movie light crew know far more about light than most high end pro photographers.
