Bruce suggested I add the photo to Dropbox so here is the link to one of the
photos that has blue sky. I am not sure why the JPEG version looks way
better than the DNG/RAW version of the file. I am beginning to think it is
perhaps my monitor and if it is then I will not be able to get a new one
until next year.

I didn't assist before, but you can send me a copy if you'd like and I'll
see how it looks on my laptop in LR and converted to JPG.

I need to ask if anyone that has assisted with the blue sky send me a
message and I will send you a picture in DNG format that I took today.
It was a blue sky day so I snapped a few pictures at work and I notice
the same issue again today in the pictures.
Thanks,

Jeffrey, I see no banding in that image, just the usual low level of ISO
200 noise. Your sensor looks very clean, but you would have got less
shake if you'd used a tripod for that shot. :-)
Here's another wild thought: is your monitor showing any burn-in
lately? LCDs often exhibit some slight burn-in or ghosting from
whatever was being displayed on them previously, especially if that
image was parked on screen for a while. This effect generally goes away
after a while (hours or days), unlike with old CRTs which burn-in
permanently. This occurred to me because while I was examining your
image I saw what I thought were some regular horizontal bars, but when I
moved the image the ghosts stayed put. They turned out to be from the
Terminal windows that I have up all the time for coding.
Anyway, my take is that the images from your camera are fine.
