Agreed. I wonder how good this model is at filling the skin tone of someone. It would be sad if (for example) it turned everybody into white people or something like that.

In biometrics, there's been similar cases of software like face detectors and face recognition working very well on people from China and not very well for other people, because all the researchers who trained those models only had available large public databases from Chinese universities. The model hadn't seen any other ethnicity so its performance on "non-Chinese" folks wasn't surprising.

The boy at the beach looks very orange/blue to me and reminds me of this:
