Took my contour+2 out for the first time today as well. It was at night with lit runs. Same settings as you except I set the light condition to "shade" instead of the factory setting of "auto". This is the result.

Personally I have never really trusted any type of auto setting on cameras. Though flat light is flat light no matter what. The night time lights are a lot better then late day or dusk flat light conditions.
