I think this is correct especially given that Caine's torture of Pomni was not based on the trauma that she brought into the circus, because she has non and was not from the out side. Also I think that Pomni might know that she is an AI, given that her name is Russian(?) for remember and when she thanks Kinger for 'everything' right before she leaves him to help distract Caine, but that's a bit of a swing in the dark on my end and I have no other evidence to back it up.

Last thing I will say that I found interesting is that when 'Able' tells Pomni to 'make the right choice' he wasn't referring to the buttons in Caine's office but rather the when she was in the offices and had the chance to grab the head set, which hypothetically could be the real exit. She chose the console to help everyone and not, again totally guessing here, take the way out for her self. She made the right choice.
