How so , I see 2 perfects for OLED and 2 Excellent making it a 4 on 8 in terms of trumps over QLED. However what you are hinting out is true, that the above article seems to suggest QLED is a better overall product than OLED.
Just to give an end user perspective owning both TVs of the 2017 model (QA7F and C7) , the brightness seems to work in favor of the QLED for quiet a few sporting events but apart from that the OLED seems way better for OTT & content streamed from the PC. There are enough user & professional reviews on both so I will not stress further on the PQ.
Another important aspect which is service where LG has clearly trumped Samsung for me. To my ill fate both TVs went dead after the standard warranty period, was surprising to see TVs go bad so fast when our previous Samsung LCD TV lasted a good 10years+ and these are considered their top of the line series. LG made a workaround offer where they could offer me a 2 year extended warranty at a cost and provide a replacement panel for free which I gladly took and have my C7 serve me for at least another 2 years. Samsung refused to entertain any such thing & was quoted a ridiculous 65k for replacement panel whereas a new QLED starts at about 85-90k, add there was just a 6-month warranty on the panel. What hurts, even more, was no one was willing to take a stand and either close or escalate the issue, went round & round for 5 long months before I decided it was pointless and we are using the TV as is till it completely goes bad.
