1. Not really. A lot of it was scrapped because of scope, but you can get some variations by using the Day 10 password on Sal's route for instance. Beyond that, nothing extra.
2.The CGs shouldn't be repeating, so that's either a display error or a bug that isn't current as of the build I'm working on. As for the missing CGs, those numbers don't line up to the gallery as I see it. You 100% should have progressed through both of those Trauma CGs if you've completed the game, and the missing Memories CGs take place on Dean's route (according to my list anyway) and aren't missable if you've played his route at all.
