Which is of course false, as apart from A700 (before firmware 4), dxomark never detected RAW NR on any Sony camera

Considering DxO only examines the RAW files, of course they wouldn't detect it. That's true for all cameras. NR is only noticeable if one examines the signal prior to NR. If one examines it after it has been done already, without any prior reference, it is undetectable. IOW, short of intercepting the signal prior to the processing that occurs before it ends up in a RAW file, it is impossible to detect if and how much NR is being applied to the RAW. And only very few are capable and have the equipment to do so, generally speaking the camera manufacturers themselves, a few chip makers, and a few scientific laboratories. DXO is not one of them to my knowledge.
Kind regards, Wim
