Since your comparison is a poor one. The reason you saw few black faces is because generally speaking blacks have a lesser interest in country music. Not because they are excluded. FYI, there are such thing as black country stars. Charlie Pride got awards at a time when things were less color blind. It's the country music awards, not the Caucasian Awards. There is a significant difference between JP's example and yours.
