It appears to me that much of the 7d II's hyped IQ improvements are from the in camera JPG processing.
I shot RAW + JPG, now going back and PP a few and comparing I am not gaining a significant amount of improvement over in camera jpg.
Noise can be improved a small amount, that's about it.

That is just comparing to the jpg vs a PP raw, the RAW file itself is bland and noisy and can take quite a bit of adjustment to get to that point.
