I think it depends on the film and its age. Some films will change colors/tones/hues a little when over and under exposed... and the push or pull processing also shifts the colors a little as well.

I usually shoot color film that's new at box speed, only adjusting exposure based on the shot and the amount of shadow it has and hope for the best. When I use expired films or cheap films, I just shoot and enjoy the results I or the lab gets.

The only way to really tell is to shoot a roll and do some bracketing on shots, make notes of settings, and see what you get. I find some films will vary wildly based on a stop of exposure.
