Not sure if this is a bug or a feature, but it works differently than other skills, so worth mentioning.
If you get a dupe with the Masterworks as a default skill, they won't complete a painting. The game message is "Local colony lacks art fundamentals." Which is true, but there is a dupe with max art skill. When checking the (blank canvas) painting's "Errands" menu it says, about the masterworks dupe, "requires learned skill."
I seem to remember other skills (like digging and mechatronics engineer) not requiring the earlier levels being unlocked for the dupe to be able to do the higher-level skill they came with. A similar approach across skills might be good.
Have a dupe that starts with max art skill.
Build a painting.
