It may not be the compression but the 14 vs. 12bit file. All I know is that if you push shadows quite a bit on the A7 (and A6000), you get a purple color cast that is hard to remove.

This happens when you push the files so much that you are close to the noise floor - close to the limits of where the sensor can differ between a useable signal and noise.

When exposing properly, this shound not be a problem, not even for low light scenes. Taking some HDR exposures might be helpful to avoid poor shadow data (tons better than any Canon camera, though!).
