It's a USD denominated world on the 9F, 10F, 11F of the Lotte Department Store Building, collectively called Lotte Duty Free.
And yes, ironically, Koreans can be DCCed on their home turf on those three floors~ Paying KRW cash there also means accepting DCC or not D, but just CC...
The rest of the Lotte Department Store uses silver signing pads with DCC functionality. The signing screen shows KRW and USD when American cards are swiped.
Be aware! There is no signs on the escalators from 9F to 8F saying "you are leaving USD world, choose KRW"
