Purely by RAW, any nonstandard metatype or changeling would get this, but I think that statement is too broad. I wouldn't apply it to a changeling with no visible differences, although some of the non-visible ones such as symbiosis might still count due to how they affect the character's behavior. The drake is a bit more of a grey area. Searchers might not know of the drake form, but what about when they start digging? I might apply a threshold, then apply distinctive style if they beat it. Not sure.
