Even in those stills (cherry-picked for sure) it's easy to spot NN artifacts, it's just that most people on HN trained themselves to spot "classic" CGI problems that are local. Check the general geometry and long-distance order, that's what problematic for NN because of their nature. Even using photos as references NNs can't avoid shifting ears or gaze or warping faces because there's no concept of the underlying 3D object there, just a bunch of flat transformations.
