Hmmm. Made a render of metal with no refraction on the mat. Made the same render with a refraction of 300 on the metal. I can't visually see any difference, and my (thumbsplus)program says that both renders have the same exact number of color pixels in each, so I would say, with normal settings, there's no difference. In Bryce, with basic settings, anyway. :o
