It changes the medium. Even if it works perfectly, doesn't alter luminosity and perfectly preserves the art under the wrap, it's still shrink wrapped art and alters the experience of viewing the work.
I doubt this technique could be used with heavy impasto paintings. Wouldn't the film have to sit on a mostly flat image to work correctly? Otherwise it would cast shadows between the painting and the film.
3d printing impasto does sound cool as a tool for restoration of topographically scanned originals.
Perhaps.. have you seen the 3d replica's in the van Gogh museum? The film could also have a 3d printed version.
