Even to this day Arkham City looked absolutely amazing for a fucking PS3 game (running in 4k on a PC tho).
And Arkham knight is one of the best looking PS4 games hands down (only beaten by the likes of Uncharted 4 or Last of Us 2 etc and very few others).
E33 still looks great with all that said , but Arkham knight was a true work of art for a decade old game
