I think you're over-analyzing and you're trying too hard to justify your Leica ownership.

In my many years of shooting and printing, I still can't detect what lens was which when I look at prints, even the 16x20 prints, unless I clearly remember at the time of shooting. But still, long ago I decided that my talent (whatever it is) and my love for photography were worth the insane money I'd put into the system just for the sake of it. Just like a car Lover wants to drive a Ferrari just for the sake of it.
