I don't think art comes into it except maybe colors, but even artists use pallets or understand enough color theory to make their own. The discipline should be data driven - study what works and what doesn't, etc. but I don't think this is common anymore. UI design seems, as a field, at the lowest point I've ever seen it and I've been using computers since windows 3.1. A mess of undiscoverable stuff presented in just novel enough of a way as to make it a snowflake. I think lack of consensus around best practices and methodology would make this a very though thing to learn and be good at right now.
