I believe that the light values in this photo help to actively guide the eye down the corridor and into the doorway. I also feel that the subtle dark values give the eyes a place to rest, which gives the doorway in the picture an important function.
I feel that the wall paint serves a good purpose as the main dark value for this photo. It also has shadows that add to the darkness of the photo. It allows the lighter values to find a way to blend into the main dark value. While there is a fair amount of light elements in the picture, I feel like they help the darker images stand out in the composition.
