Its not bad but the hue transition seems to be askew.
Yes, even though I am using ProPhoto & 16-bit in Photoshop, it is banding or near banding. Perhaps the cure has killed the patient.
I was getting unnatural deep blue skies and the problem was underexposure. I was given some very helpful tips by members here.
Ed it certainly looks too blue to me, especially the deeper blue areas. I can see some banding in these areas. I suspect a Vibrance setting of +60 might be the culprit. It seems very high.

Yes +60 is asking too much
