The way the cameras adjust their iris was updated with the most recent version to avoid over exposure. The iris adjusts to make the brightest area as clear as possible.
If you notice in the before image, the roof overhang edge appears unclear because it is too bright. In the after picture, the iris has adjusted, and now iris has adjusted so that the roof overhang edge is clear. This resulted in the rest of the image being darker.
I would recommend adjusting the angle of the camera to minimize the amount of the roof overhang that is visible.
