Hi looking to by one of the LG OLED TVs. I want 55 inch so it's between the B6 version and the E6 version. The E has the built in sound bar, but I don't need that as I have separates. I see it has an extra HDMI input, which I don't really need and the glass 'floating picture' - which looks nice but not a deal maker. Does anyone know if there is any difference in picture quality or is the actual screen essentially the same?
