There are a lot of questions, and Bill Claff didn't really managed to answer them. For example, assuming the processing detected on uniform areas is a simple form of NR, non content aware, which will result in a significant loss of detail (no attempt to validate any of the assumptions are made).
Unfortunately, photonstophotos proves most useful to people always looking to bash Pentax (on the other site there are some new names "interested" in the K-3iii but always having bad things to say about it), and not at all or very little to Pentaxians.
