Sometimes. Foam science (and, yes, there is such a thing) is mighty complicated. I've had krausens linger on for weeks after fermentation had finished, and I've had brews that never really developed more than a light froth. If there's an observable consequence on the final beer product, it's subtle/complex enough that I have never noticed it.
