There isn't any new scenes in this new version from what I can tell. The difference is that you can acquire all of the Scenes with Lexy, Aurora, Seraphina, and Roxy in the same playthrough, since there are now new options.
There is more story to each animatronic now because of the new options.
Do you want me to tell you their paths to get the Scenes with them or not spoil them? If wanting to tell, reply to this post.
