Lightroom :: Defringing Nikon Raw (NEF) In 4.4?

Thin black branches against a blue sky are always problematic.  Problematic for Lightroom, that is.  The jpegs straight out of my D5100 totally eliminate all CA and purple fringing, so I know it can be done.  It's just that no matter how I play with the "Defringe" sliders I cannot eliminate the bluish case on the branches.  I go back and forth between my attempts in LR4.4 to my jpeg of the same scene and the jpeg handles it perfectly.
 
"Remove Chromatic Aberration" box is checked.  Is it maybe a fact of life that Lightroom 4.4 just doesn't handle nefs as well as maybe Canon raws?
 
My workflow is such that I have to work on a ton of images at one time, so I have a "prest upon import" set up.  Then I export as tiffs.  So I'd like to keep all the tweaking in Lightroom for efficiency's sake.  Very few of my images actually have this "problem" but in a video tutorial on the use of these sliders the commentator mentioned that the submittal of images to a client (magazine, whatever) requires that all CA/defringing to be totally done or you'd look like an amateur.  All his video did was get close, just like my attempts just get me closer but nowhere as good as the SOOC jpegs do.
