Great. I like your critical approach. Then there is another option for night mode. Instead of spherical lamps, use hemispheres directed towards the screen (the hemisphere must be rotated around the axis, I don't remember which one)) by 90 degrees, experiment). Hemispheres can be small in size and also arranged randomly, and have different colors. This illumination option is more unidirectional and will shine less to the sides (depends on the height of the hemisphere). The size of such hemispheres also needs to be determined empirically. First, make all the hemispheres of the same size, group them, and then, at the initial level of rendering quality, figure out what needs to be fixed. It is possible to move the bases of the hemispheres further away from the screen so that sharp circles of illumination do not appear. Try it yourself))).
