Would these webcams have shipped if you couldn't see white faces well on them? I don't think they would, and the test proctors would not think of requiring one that didn't. Both the camera makers and the proctors are putting in an assumption that these products are only/primarily for white people, and thus discouraging non-white people is not an issue.
