Not really... it is clear lateral CA, of the red/blue-green type. It is at least 3 pixels wide (and that is why I say the testing procedure/software seems a but unreliable), and has nothing to do with LoCAs nor purple fringing...
Look at the fifth image for instance, it is all over the place but most clear on the left top, the mountain/sky edge where depending on angle of the edge angle we either see red or green. And the snow patches, red on one side, green on the other. Typical LaCA where some colours get bent more than others through the optics, resulting in some colours having larger projections than others.

I will have a look regarding the CAs in the "corners". The effect amplies more towards the extremes, of course.
This will have to wait till next week though. Some scuba diving in Norway is waiting for me. :-)
