Surely the lighting matters but I think it is only secondary. The thing that's missing in reproductions is the physical texture of the paintings.

I'm thinking super high-end 3D printers in 10 years will solve this problem.

Detail-wise 3d printed reproductions have been decent enough for a while I think. The trickier part is mimicking the texture of complexly layered and blended oil-paint with filaments.

I'm not so certain. Up close, paintings are complex 3D sculptures made from a palette of materials, (not colors), each with varying levels of translucence, different reflective properties, different textures, etc. and they can be combined and moved around in infinitely complex ways.

Might be possible in a few decades, though.

They’re doing this! Read about the restoration of Rembrandt’s The Night Watch (https://www.rijksmuseum.nl/en/whats-on/exhibitions/operation...). Amazing tech.
