What result (value) do you prefer?
I think I prefer dark level 2. The difference might seem minimal on these small pictures, but will probably be a lot more visible on a larger image.
changed the behavior of the default global illumination to have a minimum nighttime brightness for a sky texture. This option is disabled for a sky color because it changes to a blue hue that varies with time.
I did a Gamma Correction on your last images, and got this result ( used black background for easier viewing):
On the two lower images I can see there is a blue hue that is more visible on dark level 1 than on dark level 2, but it seems to be the other way around on the two bathroom images. Does this have anything to do with sky texture or colour?
BTW: It's amazing how well all the details are preserved, even if the rendering is very dark.
