I wouldn't quite put it in terms of real or fake, but I think you're absolutely right - that actually the term is kind of broad, covering those who like "risk" and find it spicy, but might even be shocked by being actually seen, and those who really want to be seen.
I really like the idea of two paths, although, maybe not in the boss scene. The view I had was that it was possible that Emma just fancied Catherine a lot and I had thought to even go into a little light domination play there (although, main character must have agency). Perhaps some opportunity for her to be "actually" seen.
The reality is that I've already got multiple paths, or at least I try to adapt to player choices. I've been writing 3 different versions scenes for the players preference with sister, for example, not wishing to punish players for not wanting to... umm... directly... play with her.
