I wouldn't be able to detect the difference observing the print, but technique certainly has an interest for those "in the know". And certainly ultimately it's the not the technique that determines the value. But it is not irrelevant information I believe.
Not a claim of superior quality. It's just a description of the technique used.
I agree......since there are so many ways a photograph can be produced, a label to describe the particular technique is informative, if it confuses people, then so be it.
