It sounds like you know more of this than me. Do you have any specifics in mind about the change in the concept of individuality?
That said, I also see Peterson as clearly adding much less than Nietzsche (if anything at all) on pure philosophy. He is a psychologist, first and foremost, that happens to draw on some concepts from philosophy and biology (developed by others) for the purpose of providing a path for people (mostly young men) that have lost the sense of purpose.
In this confrontation with the inner emptiness, he seems to grapple with the same problem as Nietzsche, but with a more practical approach.
Indeed, as a clinical psychologist, his task is precisely to formulate it in a way that can reach people.
For those who have never had any serious struggles with the problem (nihilism, lack of purpose), he probably looks like a quack.
