I understand this but we don't know how did those "experts" obtain raw data they tested. even DCU does not show the REAL "raw" unless you do some setup after opening the pef image, what about other programs
As I said, they wrote their own software to look at the data itself. These people do know exactly what they doing.

If they used DNG then it's not even a "real" pentax RAW.
Sure it is, as far as the actual data is concerned. It's exactly the same image data. but FWIW, these same people have also analyzed the contents of PEF and DNG files to determine *exactly* what additional information is in one versus the other (and it does cut both ways).

when you open PEF in DCU it contains some NR which you can turn off
You mean, you can turn off the NR that DCU performs. You cannot turn off the NR already baked into the RAW data. This is what the people I mention have proven by analzying the data itself, not just performing experiments using programs written by other people. Unless you have written your own sotware to analyze the data and have somehow come to a different conclusion, you basically cannot possibly refute their findings. They have looked at the data itself; the rest of us have not.

When I open the same pef in irfanview, for some reason it contains the same default NR but you can't turn it off.

this makes no sense unless they keep full resolution jpeg in the pef which is unlikely
There is indeed a full resolution JPEG in each PEF file.
