I don't know aside from the official Support Forum. There is this one that's at "full bright" but a lot of the subtlety is lost:Where can we find a screen with the advanced night lighting? I don´t have the 737 yet.

The actually lightmaps are the same for the released and the "advanced" versions, it just that the advanced takes advantage of the graphics card's onboard processing and use of shader blending modes. It's faster and better blended.
