I think that's true to an extent, but serious errors such as the woman with what looked like a horn growing out of her cheek to match a partially-occluded earring seem to happen often enough that they would call attention to people being fake.

Apart from happiness (smiling), all of the deep fakes showed a blunted affect. Genuine humans tend to have quite expressive faces, and the many of the fakes looked like NPCs from an Elder Scrolls game.

These lead me to believe that a situation where deep fakes might matter e.g. security video presented as evidence in court, it would be possible to start picking up the deepfake artifacts/signatures even for a human expert.
