King seems to be wrong. Washed sky is usually the result of open
aparture.

Nonsense. Aperture alone has nothing to do with this case. Stopping down
does not extend the range of sensor sensitivity. Aperture and shutter speed
together determine correct exposure.

There are only two applications of aperture which effect exposu 1) when
one opens wide enough to cause flare (in a lens so susceptible), and that's
generally not considered a good thing and 2) when focusing close enough to
throw the brighter background far out of focus because a focused image is
(generally) less bright than a focused one.

In this case the range is too great for the sensor or the image was
underexposed.
