I'm pretty sure the gallery scenes are still stat dependent for what variation plays. ie if you replay the rain rape scene, you'll still get a different version depending on if you have enough deviance to enjoy it or not.
of course, the cheat menu is always available, so if you're just gallery surfing you can adjust as needed. Though, it would be nice if the scenes told you what variations were available.
As far as I'm aware, Defiance doesn't govern whether Claire enjoys a scene or not. That is Depravity based. Defiance governs whether the scene actually happens or not.
This is one of the major flaws of the sytem for me so far, because it deprives the player of agency. When your Defiance is high, Claire will automatically fight off certain assailants (in other cases, usually game over scenes, it does not matter). So if you want to see those scenes, you'll have to keep your Defiance low. At the same time, you *need* a high defiance in order to do certain questlines (Mercenaries come to mind), becaue you'll get a straight up game over without it. That means you'll have to find a very specific way to increase your stats to do some stuff, and then decrease them to do other stuff. It's possible, but tedious and counter intuitive.
You could of course argue that this is intentional and you should do multiple playthroughs with a shifting focus on what kind of scenes you want to see. Fine, but not the approach I would take.
I think the system should be change to include both Defiance and Depravity/Seduction in decisions like that.
Example: Claire is assaulted after her waitressing in Valos.
a) Defiance is LOW: Claire can't fight off the attackers. The scene happens, no matter how depraved Clair is. The Depravity will only regulate, whether Claire hates or enjoys the ordeal.
b) Defiance is HIGH + Depravity is LOW: Claire fights off the attackers; the scene doesn't happen.
c) Defiance is HIGH + Depravity is HIGH: Claire gets to choose - she can fight off the atatckers, because she's not in the mood, or she can give in to her depraved urges and let it happen anyways.
Scenarios a) and b) are already in the game, and they make sense. c), however is currently not possible.
With a change like this, agency is returned to the player, based on accumulated stats. It's also more straight forward for the general mentality of an RPG player, where higher stats=better.
