A:Answer I own a older Samsung Tv. I have been researching into a purchase soon. I looked at reviews of the OLED and they will give you the best Black of all 4K but not the brightest pic and vivid color as the Samsung and Sony. Samsung is the most Bright, Sony is more Natural, and LG OLED has best Blacks and avg color vibrance. But go with your own preference. I'm looking at the 9800 Samsung for Full Array Back lighting. I don't want curve though. Sony is good and flat but would have to spend 5k for that TV. Samsung is 3k for Full Array. Most of the 4K TV's in the 2-3k price range have back Edge Lighting which is ok but not the best. For the best price and quality if your Ok with curved, this model is the best. Otherwise, Sony for same price you will get edge lighting back. Good luck.
