Most of the scenes in the gallery are affected by whatever stats Claire currently has; just adjust your stats for the latter.
The former I'm not sure what you're talking about since the only Ranger who willingly engages in bestiality (that we're privy to, apart from Claire if you've elected) is Roxanne, and her scenes are definitely there. The scene with the Ranger being raped by the tiger while Talin is forced to watch and assaulted is also in the gallery, so... again, unsure what scene you're referring to that isn't there...
Other than the demon/incubus scene (which evidently was intentionally removed since it was supposedly a collab that fell through? The image files are still there... Dunno, I could just be forgetting which quest initiates it, it's been ages since I bothered with doing everything possible in a version), everything is there.
