It's proprietary so you cannot test for it
AFAIK, it's corrected in RAW processing, so if you don't shoot JPEG, you can process images without correction and test for it, just like photozone does.
This seems to be the trend of the future and the idea is to focus on sharpness and let distortion and CA be corrected in software. It's always easier to optimize a single parameter than a bunch. Correction of distortion and CA can lose some sharpness in the borders, but if that is high to start with, the result will still come all right. And I imagine that not worrying about these issues can also simplify the optical design by eliminating the need for corrective elements.
So this lens would have to be significantly sharper than the current kit lens, but if that is not the case, I don't know what its point is.
