Dawn and dusk: sky color and brightness

[Picchio]

One aspect that I've been observing on DCS' skies is that there seems to be a too sudden (and not realistic at all, I think) transition from and to the night sky.

The sky gains or loses color and brightness just too quickly, turning grey and then black (or vice-versa), without the blue tint that would be normally observable in reality.

Normally, sky colors in DCS are very convicing, except for these two (critical, I think) situations... could use really some improvement!

Replying to myself: the issue is still vividly present and makes dawn and dusk gameplay quite a bit alienating.
