Yes. Once you max a girl and do all her scenes at least twice, you'll end up in a special event with the girl. This is called a "State Event". Through a series of questions and answers, the girl can end up in 1 out of 3 "States" which can be catalogued as Best, Good and Bad and depending on which State she ends up with, the scenes are gonna change a bit or as of 0.16.2 (this latest update) a couple of them are gonna be only for one state in particular so to see ALL the scenes, you'll need one savefile with the Best state for each girl and another one with the Good state for each girl.
This is the reason why a "full save" is straight up non-sense cause normally you wouldn't be able to see all of the scenes due to the States thingy, only way to get a real "full save" would be to edit the savefile and toggle the scenes in the "Mind Palace", which is the pseudo gallery that only contains the unrepeatable scenes.
