From what I've seen on the art side of things, the more a certain work has been copied in the real world (and thus in the training set multiple times), the more likely it is you're able to get a very close copy out of the model with the right prompts. For example, I'm pretty sure this is why some models turn up a near exact version of The Girl With The Pearl Earring.
