Art style and graphics definitely have some impact on how much I enjoy a particular game.
I don't think a game's art style would ever hold enough weight on it's own to dissuade me from making a purchase. For example, I would go out of my way to say that Return of the Obra Dinn's art style is awful. Sure, it gives the game a certain ominous tone that is fitting for what it is, but at what cost? Regardless, I still purchased the game and have enjoyed what I've played of it so far.
I do have a soft spot for 16-bit style games, like Stardew Valley, Moonlighter, Binding of Isaac, and Nuclear Throne.
But no, I don't think it's ever been enough to make me not buy a game that I otherwise would, at least consciously.
