No one puts a special label on gifted athletes, artists, etc. though like they do on people with high IQ's. If such labels did exist, they would probably turn people off in much the same way. It comes across as arrogant or bragging.

I use the term on forums like this where just about everyone is in that category, but will not use it with people not in the category. Or I will use it to describe the programs at school because that is what they are called there and there is no other term.
