There's definitely people out there with that potential but I doubt there's anyone who has achieved that skill level unnoticed. Without playing competitively at that level it is impossible to achieve that level of play because without being faced with opponents of that level you couldn't develop a level of play to beat opponents of that level.
I know I don't have the potential to be that great but I could be better than I am although probably only moderately so. But people with that potential are definitely out there. Name any grandmaster. Now imagine they never started playing chess. They'd still have the potential to be great but it would be unrealized.
