I think the tonality "issue" when trying to lower exposure of a overexposed sky is due to the fact that the closer we are to clipping all the channels, the harder it is for an individual channel to stick out and be visibly dominant. When we, in post, drag our sliders down, we are stuck with values that's perceived as closer to a "tinted light grey" (240 240 255), than a "subtle blue" (170 170 185).
How about that as a thought?
I think it has something to do with blue being the 'weakest' or 'darkest' wavelength of light, and the camera processor is applying more amplification to blue.
Certainly red and green are not as effected by overexposure, but it is there if you are extreme enough.
