It's a tech demo. Let us treat it as one. For faces, skin, and hair (so everything human) I personally dislike the direction. But for environment, props, and especially lighting, it's quite nice!
I think that's more an issue with their AI model though and could be fixed in the future with a different model. Some diffusion models have a similar fake brightness / studio lighting issue, e.g. Imagen 4, others don't (Imagen 3).
