The message UPN sent out in this broadcast is that White actors make less embarassing mistakes. They know their lines, they're professional on the set. There is nothing bad to say about 'em. In fact, the producers of this show were forced to dig into the vaults for 70s gameshow footage as a sort of Affirmative Action when the only three mistakes that ever took place on the set of Enterprise didn't fill enough screentime.
(Let me assure you, if my sarcasm wasn't thick enough, that none of that last paragraph is in any way true. It's just the undercurrent present in tonight's programming...)

They probably meant well.
