I furl leaders and have chosen to not use tippet rings - not because of the flash - just as a matter of personal preference. I don't believe that the glare from a 2mm ring would scare many fish but that is merely my unsubstantiated opinion and nothing more. As to raising the question - I see absolutely nothing wrong with that. My 75 year old fishing partner and I fish daily and some of the fun, I believe, is pondering even the most minute details of our sport. Soooooooooo PONDER ON BROTHER - PONDER ON. Right of wrong there are a lot of us right in there with you.
