The CA procedure works fine within its parameters. Technically it is slightly polluted by LoCAs but even so it is meaningless because a color fringing is a color fringing regardless of its origin. You may argue about the naming of the "combined CAs".
PF is another issue as mentioned but not measurable. It is probably the issue that you're pointing to here.

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.
