The WGT scorecard length is measured to one hole on Par4s and Par5s - @KIA#9 it's the front hole. You probably played to the "new" pin in the back - obviously longer but it doesn't show on the tee.
Furthermore, this is a dog leg - you won't play on a straight line.
The true distance is shown when hovering over the blue dot on the mini map, or after whiffing the first shot (take putter).
