Re: Dropoff seems like a greater problem to me...

I'd need to shoot something a bit more diagnostically useful. I can certainly say they aren't using the same distortion correction as the JPEGs. There is a free trial of DXO so others can play too...

It could be that DxO tries to rescue more of the uncorrected frame than the jpeg engine or other RAW converters would. As you can see from the thread I linked to, it seems that the standard procedure is to chop off slightly more than would be required to get rid of the distortion. But I wouldn't think the distortion left behind by DxO is much different from that left behind by other processing alternatives for the simple reason that the latter get fairly close to the zero-distortion level.
