I've always heard the "too smart to know I'm smart" as manifesting differently. Getting better improves two distinct sub-skills: excution, and perception of performance flaws. Dunning-Krugar effect, to me, just says that flaw perception grows faster with skill than execution does. At a concrete level, I remember watching a lecture from a Jazz instructor by the name of Hal Galper, who said something like "Not liking the music you're playing is a sign that you're getting better, since it means you can now hear the mistakes you've always been making". It's really stuck with me through learning other creative pursuits (dance, in particular).
