The RAW converter CA adjustment did have some affect on the blue and
yellow color in the out of focus branches, although it didn't eliminate
the effect completely.

I used to get a little CA on images taken with a 'K' 300 f4 of
Superbike
racing in the UK, now completely abscent using a Sigma 300 f4 APO
even with a
1.4x EX TC attached.
Just because CA isn't evident at the plane of focus doesn't mean it's
not a
form of CA, it's certainly not a bloom artifact in the image under
scrutiny.
