Yeah, that's REALLY stupid. "Look really carefully at this picture so you can see some tiny, almost unnoticeable habit, and if you can't see it the first time, watch again and again and again." At least the psyche locks in parts 2 and 3 had some sort of logic to it - you were actually solving puzzles you'd gathered clues to - looking at sprites for small animation changes is just distinguished mentally-challenged.
I'm on case 3 now and the game is still completely MEH. They even removed the feature for presenting profiles. Worst Ace Attorney game ever.
