Arun,
You demo'd both B6 and E6? Did you find any picture quality difference?
No, only the B6 unfortunately. To be honest, to my eyes, it was everything I needed, and after use, I do not see any limitations (also i have a separate audio system so do not use inbuilt sound and was not looking for it either).
The ARC is sometimes a bit glitchy and WebOS could perhaps have some more apps, but neither of these seem to be specific to B6 model itself. In terms of picture quality and performance, I have faced zero issues, even when playing 4k HDR.
