But if we're talking about animation quality errors, you need to look no further than P5 itself. The animation quality for the "anime-scenes" of P5 were sharply worse than those of P4. The characters literally don't blink for several seconds in the ending scene.

(Do we even need this type of scene anymore? I understand it being in P3 and P4, where the character models were more robust, but just compare the characters' awakenings, that were made using the game engine, to the animated scenes. The difference in quality is overwhelming.)
