Never encountered this. Is there a context were it really is used as such? (or is this a translation issue?)
The roots of developer is literal code writing. Hence only Software Developer, Web Developer, Videogame Developer are called developer. That is not a descriptive usage, like creator would be. If you create other stuff, you use other words. Like movie producer, painter, singer or even voice actors. Even if a voice actor develops a nice voice for a character, I would not call the person developer in the descriptive meaning. If I need a noun, I already have "voice actor".
