There's an issue I've noticed consistently with the Revitalization's portrait changer: In plenty of dialogue, especially Galatia-campaign dialogue, there are gender-specific callouts for the player. Now, I have a sort of "template" savegame to carry over some personal/manual touches to the sector, and it seems the portrait I started that with is classified as female for the dialogue variants; but even if I change the portrait to a male's, the dialogue is still in feminine appositives (ma'am and madam).
It also seems that whatever defines the portrait's gender isn't tied to the player.faction file, since I changed some helmeted portraits around but their appointed gender remains as they were previously...
