Re: Same image – like night & day - a miracle?
Is there any rational explanation for this peculiar abnormality?

This is a "normal" behavior of the renderer.

The default global illumination uses Ambient Occlusion and its parameters allow to have at daytime a minimum luminosity in a room completely closed.
So at night, without additional lighting, the image is black.

P.S.: At daytime, you have the same effect with diffusedBounces=0.
