Interestingly the higher-end physical movie releases have moved to metal cases and/or paper sleeves to hide the plastic. Perhaps that's also what digital music would have moved to if the physical market didn't get eaten by streaming. The artwork would still be smaller than vinyl but if you have broad tastes and limited space that may actually be a feature.

I'm just saying there is a market for vinyl records with no art or sleeves, but no market for sleeves and art with no record.

Clearly the art isn't the driver of this market niche.
