Another photo taken that day by the aircraft a little more to the East, showed the submarine base. There is some overlap with the first image. Note that the contrast of ships in this photo is different than in the first image, which is likely the result of print processing and a slightly different aspect angle to the subjects or less likely adjusted camera settings.

As a reference, this image was reported as taken on 10 October 1941 and shows the overall area of Ford Island and the surrounding anchorages. Note the direction arrow as to North.

If you look closely, you can see that the 13 October photos were taken at nearly noon resulting in shadows from overhangs on the ships depending on the aspect angle that the ships have been moored at.
5-D (and for that matter so did 5-N) paint faded and chalked along with salt residue on most surfaces. The hull really exhibited more wear and fading/chalking/salt than the superstructure. Plus, the crews could more easily "touch-up" the superstructures even while at sea.
So yes the superstructure of USS ARIZONA and USS NEVADA would naturally look darker than the rest of the ship and her hull.
