I don't think this is true, Apple hasn't openly said they do this level of manipulation (although that doesn't mean they don't necessarily), and I don't think the range of motions she would have to go through would be possible within a single capture. Even with "Live Photos" this wouldn't happen.
I’m also skeptical. I want it to be true, because it’s pretty wild, but it seems a little too perfect. I suppose people must already be trying to prove or disprove it.
