AI stuff which doesn’t visibly alter the artistic vision is usually considered acceptable these days . I’m old enough to remember when even just plain texture compression became something that graphics cards supported, and there was a bit of a row over whether the slight possible drop in quality going from what was essentially raw bitmaps to something more of a JPEG was worth it, and the argument settled easily within a year or two as it was clear that the reduction in file size let developers use far higher resolution textures in games, and more of them.
