Just had my LG delivered yesterday, I got it to replace the Samsung 65 Q6FN QLED TV I sent back due to a cluster of distracting dead pixels. Comparing it to the Samsung, colors are almost as good but blacks aren't nearly as good even though the Samsung was edge lit, I kind of expected this due to the LG's IPS panel but I had thought the FALD would help make up for it more. Blooming is crazy bad, I never experienced blooming until this TV and now I definitely know what it is. In well lit scenes it looks much much better and the brightness is just "enough."
That aside, motion is way better than the QLED in every way and gray uniformity is darn near perfect unlike the Samsung which had some nasty dirty screen effect. Gaming is perfect and build quality also seems way better, the Samsung would make plastic popping sounds as it heated up and cooled down. My only other grip with the LG is the weak wobbly stand it's on but it's up high so I'm not worried.
Off topic but I don't recommend purchasing a large TV from Amazon, they provided return shipping for the Samsung and had UPS pick it up. Well UPS lost it after it landed in Arizona and Amazon won't refund me now, had to dispute the charge with my credit card. The LG I got from BHphotovideo as they have always provided great service and use ABF for shipping.
