I agree to an extent, though I feel it's one of those things where if you notice it once, you'll always notice it; so people's reception to it literally comes down to whether they've had this conversation before or not.But still, most won't notice or care. Especially for a fantasy background.
I likened AI to autotune earlier and I think it's similar in this sense too: a lot of casual listeners will have the radio playing in the background and won't even consider that the voices they're listening to have been digitally pitch-corrected. But as soon as you become conscious of that slightly uncanny robotic pitch bend once, you'll start noticing it everywhere, especially if you're listening to music from the mid-to-late 2000s where record producers really didn't know how to cover up the tells.
Again I don't have an issue with the use of AI art, I just think the creator should have done a better job with it.
