Style is largely in the eye of the beholder; SD1.5 was used to make a lot of images that looked like Greg Rutkowski, and people presumably believed they looked like his style, but he wasn't in the training set and it was a coincidence. Of course this is mostly only possible if you limit yourself to looking at digital art. A JPEG of a gigantic abstract art oil painting is pretty different from the real thing.
