As far as I can tell, it really depends on the intensity of the "slider".

When the insensity of the style transfer is pushed mostly to the right (high), it just seems like Pixar or cartoons. Nothing uncanny whatsoever.

But when they show is about a quarter of the way to the right... it's utter nightmare fuel, like plastic surgery taken way too far. The worst kind of uncanny valley, so I definitely agree with you there.
