Yes, but is it worldwide then?
Every label will sell their products worldwide, but it’s not a worldwide release, only because of the fact that is shipped worldwide.
Smaller labels have often replaced their own web shops with Bandcamp. I wouldn’t call such releases worldwide though.
It would reduce the number of worldwide releases significantly. But there are still very few cases where “worldwide” probably comes closest to reality.
