That is not the case, a camera profile is used to modify the colours
saved in the RAW file when they are turned into what is displayed on the
computer or stored in a colour-corrected TIFF, JPEG etc. The profile is
produced by looking at the colours the camera shows for a known set of
tiles in an image of a colour target, it will be specific to the
lighting so you need more than one profile depending on the colour
temperature you are shooting under.

You will never see the corrected image on the camera's own screen
unless you re-upload a colour-corrected JPEG to its storage.
