Have had this TV for a couple of weeks now. It replaced an added more expensive Samsung ue65ks9505 from 2017. So far mighty impressed with the picture! Netflix series in Dolby vision looks fantastic. The colors (and of course the black level) are brilliant. Picture looks good from a very wide angle. It also decodes Dolby Atmos and can send it to soundboard / amplifier via eARC. Regular ARC will not be able to transfer Dolby Atmos, and one will not get the good sound from apps like Netflix. Haven't tested this feature yet, but nice to have.
WebOS is also much more responsive than the tease of Samsung. A minus is that the Canal Digital app is not available for WebOS. The brightness is not quite on par with the previous TV, but more than bright enough. The screen also reflects very little light, so lights that were annoying on the previous TV are far less visible now.
Can never imagine that I choose anything other than OLED TV in the future!
NB! Also works very well for gaming. Very low input layer in game mode. Playstation games look great in HDR (for those games that support it).
