What is the ISO? Did you apply a lot of sharpening in pp?

The ISO is 100. The image is a screen grap from RawTherapee. No PP had been applied. I just looked at the image.

A sensor makes colour noise, due to the CFA. Your image sample shows noise reduction gone bad. Can you show the image without any "processing" going on?  RAWTherapee clearly is doing something to the noise here.
