Xbox series x question

Will all the games that are on Xbox one be graphically updated to be at least the level of xbox one x?

Take for example Witcher 3 which is my favourite game, will it look like the xbox one x update version because the game came out pre xbox one x.

edit: xbox one x enhanced games is what I’m referring to (Witcher 3 for example)
It should have a performance option and a graphic option
