My two main reasonings for wondering this are:

• In her main hall camera render, her left pupil is noticeably way smaller than her right one. Though this is the only time it's ever like this in FNaF 2. It's also interesting to note that, despite her being visible in the camera without the flashlight turned on, we don't see her eyes glowing. Unlike with Withered Freddy in Party Room 3 who has visible glowing pupils without the flashlight being enabled.

  
  
  

• In both UCN and the second movie (for the very brief scene we see her beakless face) she doesn't have white pupils, just empty black eyes.

Now in HW and AR she definitely does have glowing white pupils, that's pretty clear. But what I'm wondering is if her original FNaF 2 model ever actually had white pupils, or if they were just the result of a weird lighting quirk. Because it seems like following FNaF 2, any time Scott is actively in control of the character, he makes her eyes just black with no pupils. And it's just started to make me wonder about this relatively pointless detail that's only important towards the likes of me.
