Question about Samsung QE43Q60AAU

Good day I have looked at the two almost identical Samsung devices: 579.- Samsung Series 6 Q60A (43 inch) Ultra HD Smart-TV WLAN Manufacturer No. QE43Q60AAUXXH 562.- Samsung QE43Q60A (4K, QLED, 2021, 43 ") Manufacturer No. QE43Q60AAUXXN Before I order, I would like to ask where exactly the big difference is. I have tried the "Compare" tool at Digitec, but it is very difficult because many details are missing for one series. Thank you very much for your feedback. Greetings
