That's an interesting analogy, because the lighting in art galleries is not at all neutral. Most galleries point a few narrow spotlights at each piece on the wall. The spotlights are warm and incandescent, and their narrow spread illuminates the center of the work more than the edges. This makes the work look like it's emitting light. It has an enhancing effect compared to normal flat interior lighting. So the actual lighting in art galleries is more like the warm distortion of vinyl and naive tube amps, not high accuracy of this amp.
