Mine also came in last week and I am very pleased with it! Both sides of it were easy to plug in and it makes my build look much cleaner.
Here is what it looked like before getting the CableMod adapter and cable:
OLEDs use the sample and hold method of refreshing their picture by default so they'll still have motion blur from that and won't match a CRT in terms of motion clarity. The LG OLEDs from C8 on have black frame insertion but the refresh rate that it works at depends on the model.
