Thanks for the explanation and your patience
I totally understand the RAW file points you've made and the associated issues.
I also understand that the Bayer Sensor JPG's on the X10 are good SOTC and require little, if any, adjustment.
I also understand that JPG's are not really the right file format to run PP against as they are already processed out of the cam. To effectively process them twice (once in cam then again in a PP application) creates degradation in the quality of the image. In 99% of cases it’s the RAW files we want to process in PP to create a professional end product.
What I'm still not understanding are the JPG sensor differences you described. You compared the X10 Bayer JPG's as;
So in response does this mean that if I took an X10 JPG and an XTrans JPG and ran them through an identical PP workflow the X10 JPG is likely to react to, and look better at, the end of the process?
