That entirely depends on development, exposure, and the scanner operator. I can make ANY film dead nuts on. That is a property of the tonal curves that are applied to the film when they are scanned. There are only two ways of getting perfect colors. One is to have a fully color managed system (as in shoot a chart with each roll) or adjust the colors after the fact to match something. Well, OK, there are three. Luck. Different scanners require different curve adjustment to get "correct" color, even with the same film. And, as I've said, exposure and development will vary enough that will make even canned film profiles not very useful.
