Considering the movie was rendered out at 23.97 fps (my source is Craig Good, who was the Supervising Layout artist for the film), the scanned film is most likely going to be the former frame rate.
I don’t know what you mean by that? Toy Story is 24fps it doesn’t matter how it was rendered in the computer before film-out. An example might be if you run a camera at 120fps for slow-motion footage, it was captured at 120fps but the film is 24fps.
