Even a "white" shirt in sunlight should show some detail BUT if you were printing onto a newsprint using a web press you would expect that the coloration of the paper would in effect provide a reader with an appearance of detail in very white areas and would expect to get away with setting a white point for something like that white shirt in direct sunlight.
For printing that is directed toward display, I would myself want to leave some tonal detail in the white areas.
As for the dark tones, the one thing that really catches my eye here is the fact that the shadow of the lamp post completely obscures any detail in the road where it falls; and you can clearly see that this is the result of post processing by the way the shadow bows in at the point where the lighter part of the road runs under it. Clearly, there are lighter parts of the shadow that have completely disappeared; but there are also darker parts that are much darker than we would expect the human eye to clearly see on a bright day like that.
