While we're all pixel peeping, here is something I discovered while examining K3 RAW files at 100% in LR 4. Looking at thin lines, such as bare limbs on trees, in the corners of the frame while switching CA correction on and off, I found the subtle but visible stair steps in the pixel structure that are generally masked by AA filters, and revealed by the K3 sensor, disappeared when CA is switch on. It seems as if Adobe is introducing some 'softening' in the image along with the CA correction. It's subtle but it's there.
