Sorry, that came off a little more oppositional than I intended. While I do parallel Semblance with individuality, and thus with personality and experience, I would suggest that there are many people whose personalities are very similar, only varying in very slight details. As a result, and bearing in mind the very wide range of Semblance powers, lots of people have Semblances which can be functionally interchanged, and would require a specialist to distinguish, with careful experimentation and observation, as well as controlled conditions and very precise instrumentation,which can only get so good.

An analogy: Everyone is a different irrational number, and a unique Semblance, but the degree to which Semblances can be usefully distinguished only has so many sig figs. Beyond that point, they vary trivially, and they're experimentally the same.
