The one with the central section raised higher is being used on a dry track, the one with the slightly lower central section (and probably producing a little more downforce) is being used on a wet track, wet weather set-up generally requires a little more downforce. Perharps there also trying to find ways to create a more efficient rear wing, teams have been varying the cross-section and shape over the width of the rear wing for years now to get maximum downforce for minimum drag penalty. What I find very interesting is how the endplates appear to 'bend onto' the the tips of the underside of the flap.... I dont think I have ever seen that before...
I'm not too sure what your describing about the endplates, but Renault ran similar endplates a few years back where the endplate is "integrated" in to the main rear wing elements.
