How are the panels now compared to the 2015 version (EF9500 if I remember)? Have they improved? Looking at a C8 and did not see any noticeable banding or vignetting on the BB floor model with some of the settings turned down and in standard / cinema modes. It might be there, but I could not see it on the content they had. I'm buying through Cleveland Plasma, so returns may not be as easy as say Costco, so curious what others thoughts are? My hope is they have improved it to some degree. This, coupled with a much lower price tag makes me think it's worth it now.
Also, why is the Sony so much more? I did not see a noticeable difference between the C8 and A9F. Certainly not a $2000 difference.
