if your take a image of something dark (such that it occupies most of the frame) at ISO 3200 RAW, upload into DPP, push the sharpness to +10, view at 100% or 200%, do you see any concentric banding?
Just pixel peeping for fun...

- just realized that this is due to correction of barrel distortion. RAW also corrected for barrel distortion in DPP automatically.
