The screenshots you posted are slightly different time of day, this one here is the same time of day as the new E3 one:
The sun is fully visible just above the horizon, just like in the new one - so it's the same time. It's pretty clear from this that they improved their lighting: it seems the position of the sun previously didn't correspond with the actual light source (which would expain why it was so dark even when the sun has fully risen), but now it does. And they added a lens flare.
It's a little weird that the clouds look exactly the same in my picture and the E3 one, though. Aren't they randomly generated? If they are, then isn't this just a bullshot that combines multiple screenshots?
