Almost certainly not AI gen, it's shot with a 35mm lens (quality looks like the 1.4 L to me), probably around f8 given how the DOF falloff happens, heavy forward flood (flash or otherwise, but whatever it was it's defused) and then what's I think giving you the sense it's AI is it looks like they've over used a double S curve to bump the contrast and sharpness. https://www.youtube.com/watch?v=XZh_9HnO_4w&t=640s
