It's actually pretty easy to simulate: Just downsample a HDR star 
background into a single pixel (make sure to use linear math, i.e. at a 
gamma of 1.0) - that's the colour a perfectly white convex object (e.g. 
a spectralon sphere) would have.

In other words: It would appear somewhere close to pitch black.
