Here's a picture taken last night at sunset with the camera in "Bestshot : Sunset" mode (emphasizes the orange in the sky to make a more "interesting" look)
And here's the same view without the sunset mode to show what it represents as I saw it with my own eyes:
I think the first one looks like what we had before that "lighting changes" patch, and the second one looks more like what we have ingame now. Ergo, I find the ingame sunset MORE realistic than the bright orange one.
HOWEVER:
The sunset with colours vary a LOT depending on weather conditions, atmosphere etc and what time during what time of year you are looking at it, so....
My conclusion: One can only wait until the weather model has been completed and see if this impacts the way sunsets look
