So I had the Samsung 8 series led for testing, picture quality is really nice with lights on but when you turn lights off the colors look little washed out and there is light bleeding in the corners of the screen. So back it goes even though I really liked the bigger screen size. LG B8 has some really nice colors and no light bleed issue in dark like the Samsung, that was expected tho. I would say that the B8 gets really close to plasma TV's for the picture quality but falls slightly behind. For most of the scenes I would say they are almost the same, but for few scenes I would pick plasma hands down. I think for one scene I actually preferred OLED over plasma. Will see how I start to like it when I have more hours on it.
