I don't know of any was removed but there's definitely some present in P3FES.That's what I'm the most curious about at this point. If I recall, didn't they remove some transphobic content from Persona 3: FES. Maybe there's hope that the same could happen with Persona 5 Royal.
I can't find a screenshot with the specific line I'm thinking of, but it's this scene. Junpei takes the boys on "Operation Babe Hunt" on the beach and they go around talking to girls. The "Beautiful Lady?" here Junpei says something like "Is that stubble on her chin? Whoooooooa, she's a he, watch out!" It's very fucked up.
