I am also an INTJ! And I'm DEFINITELY not the only INTJ creator I've known. xD
This is a thing that comes up in my favoured personality system (the Enneagram types) as well -- a casual website description will often describe the archetype associated, so you can get an idea of the general kind of person they're talking about. INTJ gets described in the diagram above as "likely to be corporate leaders," but the idea that almost all INTJs go into business and lead companies is an oversimplification imo. What you can take away from that is more, INTJs "have the stuff" that would allow them to be good corporate leaders -- they tend to be creative, insightful, and have a lot of drive. Those sorts of qualities can serve you in a lot of different fields, including artistic ones.
Heck, the website itself says:
People with the INTJ personality type are imaginative yet decisive, ambitious yet private, amazingly curious, but they do not squander their energy.
I don't know what would be unartistic about that personality type -- it sounds like they could be an artist to me! The site even lists Christopher Nolan, a creator, as an INTJ! There's no reason art and logic should be at odds -- not being ruled by emotion doesn't mean you don't have emotions or ideas you want to express.
