Dorothy really wasn't trying to be pretentious with her knowledge of art this time; she honestly just knows a little bit about it.
After all, in her previous life, she was just a homebody who listened mostly to various anime theme songs. Although she found them pleasant, calling them artistic might be a stretch.
To be honest, during her homebody phase, she really didn't understand art at all. Whenever she saw news about some art exhibition where a master's work sold for an astronomical price, she looked at those artworks—whose brilliance she couldn't discern—and just felt like she was a philistine with no eye for appreciating art.
Back then, her ability to appreciate art probably stopped at whether it looked good or not.
