The day is coming when the sceen will get thin enough and have the resolution to compete with large prints for space on people's walls. If the quality is good enough to replace large prints, then you can change your art on you walls to match the wall color of the day, or scroll through pictures. Already being done on small scale for desk top e-picture frames, and not that far from replacing wall art if the size and costs come down. For enough money you can probably do it today, but it may be to bulky for most peoples taste and wallet. If you can get hangable screens in the price range of framed pictures (currently not that far off for good quality framed picture), then the printed picture starts to become obsolete/novelty. But it would probably get wasted on selfies.
