I wonder if people’s perception of 'modern' paintings will change if they view them through VR.

Many modern paintings are massive in scale (bigger than my bedroom in some cases) and/or have many thick, voluminous layers of paint. Jackson Pollock is a good example. Those paintings look plain and childish when viewed on a tiny screen that fits in your pocket, as you don’t feel their scale, you don’t sense the depth of the paint and its texture, and maybe, you are also not in a suitable environment to view the arts. (IIRC some Mark Rothko paintings are displayed in dedicated rooms with dim light, as desired by the artist.)

But if you view those arts through VR, you can get a lossless, holistic view of the artwork. It can even be better than viewing in person as there is no crowd standing in front taking photos...
