Question about Samsung Qe65q8dn

Question 1: Screen technology QLED / LCD? When I compare this model (QE65Q8DN) with Samsung QE65Q80R on Digitec, the screen technology for QE65Q8DN says LCD and for QE65Q80R QLED. I thought they were both QLED. Question 2: One Connect Box Do both models have One Connect Box to avoid cable clutter? Question 3: Price Why should I pay 600.- more for Samsung QE65Q80R. Where is the difference to make it worthwhile.
