I can't comment on classical (I almost only listen to live recordings) but there's a very obvious smoothness, perfection, and lack of surprise, to AI jazz (or as it's often on YT as "chill-jazz") that is immediately apparent to anyone with even a little experience with the genre. Jazz's valorization of improvisation also means there's way more importance put on live recordings and surprise/novelty than on polished recordings which are often considered somewhat suspect even without a whiff of AI.

I've never heard an AI bebop song come even close to a live example, but I'm always open to being impressed.
