Light in a room is not a single layer.
The light you need to walk and the light you want when you sit are not the same. Do not ask one ceiling for both.

It does. How much light there is, when it arrives and its colour change how alert you feel. That effect has been measured.
Ambiance is how the room sits in that moment. A low, warm wall is closer to sunset. Dim green is closer to the quiet of a forest.
