A calibrated noise profile is created for each image in its present form independent of the ISO value, the exposure levels, or the RAW converter. To be fair, when I upsized the crops and printed them together on a sull 8. My initial tests with Neat Image were startlingly good, so I knew that I had to look at them pretty closely. Perhaps this information is encrypted and added to the metadata of each processed image for the purpose of identifying the user or object in the photo. If you are doing home video restoration or just for most pleasant viewing than most of what I wrote is not that important.
