Yeah but this is (basically) reddit and clearly it isn't racism and is just a problem of multi megapixel cameras not being sufficient to properly handle the needs of phrenology.

There is definitely some truth to needing to tweak how feature points (?) are computed and the like. But yeah, training data goes a long way and this is why there was a really big push to get better training data sets out there... until we all realized those would predominantly be used by corporations and that people don't really want to be the next Lenna because they let some kid take a picture of them for extra credit during an undergrad course.
