Indeed you are correct about this! What I think is different in these cases is that the images of the food in your examples (generally) aim to make it look good, whereas the AI art makes it looks like slop (literally and figuratively).

I also prefer the side case of actual photos of the food, which is common at delis and some more authentic Chinese restaurants; these are also being replaced quickly by AI.

Has AI art made my food less delicious - I don't think I've ever purchased food I've seen first represented by AI, but certainly the expectation of taste affects your perception of it...
