Nope, not at all.
You and Ethan IMO are stating what might not be obvious to some, and I'm sure they appreciate your extensive explanation. I understand equal loudness in the context of this discussion, but disagree.
Your assertion If I understand correctly is: You can't hear the magnitude of inaccuracy inherent in the mic so it doesn't matter.
My assertion is: I measure for accuracy, not close enough, or good enough, or within audible tolerances, so 3db matters to me even if it is not audible.
Call it OCD, if you like, won't be the first time I've heard that.....
Furthermore, IMO knowing about 3db differences can be beneficial in setup and/or tweaking even if you can't hear it in an A/B comparison.
