Re: Canon EOS R3 Baked in Raw Noise Reduction Revisited

attempt to summarize

1) was there "signal processing" (which I guess everybody agrees is NR) or not (not amount, just YES or NO) - my "hoi polloi" understanding at this stage is : BClaff says - always is, JACS say - no, not always (again - let us drop injecting adjectives here - just YES or NO) ... that is probably between them two and easy to resolve for as long as they both have the same raw files, right ?
2) can "we" measure that amount ( in situation when we do not have access to raw with/without alleged NR ) without using adjectives but using some proper metric vs a nominal ISO (or some other parameters - sensor temp, etc, etc if Canon account for that) ?

3) if it is present (YES/NO) and regardless of the numeric (vs adjectives) "measurements" (if somebody can measure or estimate) - does it really affect the end users when they (we) are NOT able to directly compare raw conversion/post processing of raw files with vs w/o that NR... ideally w/o resorting to "I do not see it" or "it looks like it is very minimal"... it is not "star eating" - so is there a direct test possible ?
