I think the brains that are cleanly male-trait or female-trait are very very rare, most are a mix but there is usually enough difference to be able to make a very good guess. Though I also do agree that gender dysphoria can have many different expressions, once you drop gender you get into a whole new world of stuffs where people hate various things about themselves (I've met people with self-described "whole body dysphoria" who are generally okay with their gender and simply hate the physical existence of their body)
