Break a High Pair for Four to a Royal Flush?
Dealt: K♥ Q♥ J♥ 10♥ K♣
Best play: Hold K♥ Q♥ J♥ 10♥.

Yes, every time. One card in 47 completes the royal, which pays 800 for 1 at max coins, and the draw can still make a straight flush, flush, straight or high pair. Nothing else on the screen comes close.
