For the sample image that was cited I'd hedge my bets on CA, the colour offset is visible in all areas of the peripheries of the image not just in high contrast areas, and it is definitely predictable so should be able to be fairly easily corrected using any capable tool. The CA problem has been exaggerated by bloom which is to be expected in the high contrast areas.
