I would like to know if there are any words that express the idea of something being "different, but the same". I'm open to interpretations, such as negative/duplicitous (wolf in sheep's clothing) but I'm really wondering if there's a specific term for this idea that something appears to be new and alien, but is actually familiar.
I realize there's an asian phrase "same-same but different", and that seems to be the reverse of what I'm looking for, as it promises something you know but is quite disparate in the end.
