This is true but orthogonal to my point. You talk about facts, my point was normative.
More precisely my speech act was performative: I'm leading by example, because I hope that others will copy my behaviour and speak up whenever somebody falsely calls winners of the Bank of the Swedish Empire a Nobel price winner. The best case outcome is that eventually the false prestige will be eroded away. (Compare with the Nobel Price for Literature and Peace, they are both widely regarded as jokes and nobody cares -- or worse in case of the Peace price.)
Anyway, sorry for this tangent, I don't want to derail the thread, the main subject of which is of great interest to me.
