High Res scans are good, but particularly for both a mural or an oil painting, a huge amount of information is lost with a scan, however high res. It's also the case for almost any other medium. To take oil painting for example: a painting is usually composed of layer upon layer of translucent paint. The way it alters light cannot be captured in a 2D scan, it is a very complex, 3D laminar object, before you even get to impasto technique. To see a Picasso in real life (or any painting) is vastly more rewarding than just seeing a picture of it. And incidentally you can see almost every scribble Picasso ever made, there's a museum in Barcelona containing much of his early work, including sketchbooks.
