The OT seems to have gotten a slightly wider aspect ratio with the D+ version.
Looking at these screenshots it seems to be a case of cropping. The D+ version has less picture at the top and bottom: http://www.framecompare.com/image-compare/screenshotcomparison/DYLPLNNX
On this one there seems to be more picture on the sides though:
