Nikon D300, ISO 200, 62 mm on Nikon 55-200 f4-5.6, f/16 2.5 sec - tripod.
The left image is the standard camera standard profile in Lightroom. The middle image is the v3 camera standard with -0.5 exposure compensation as required to get the correct rendering. The right one is the Capture NX rendering. You can see that the old profile washes out the highlights quite badly, while the new profile, similar to the CNX rendering gives a lot of detail in the highlights. You cannot correct the left image with highlight recovery or negative exposure compensation and get this detail back.
Of course, the bland, default rendering is not how I develop the image in the end but I just wanted to illustrate the effect of the new profiles.
EDIT. Here is a closeup of the v2 and v3 renderings in the highlight area. The effect is quite major as you can see.
