My personal opinion is a resounding "no". Why? Because after making a number of settings changes to my 55" B7, it looks fab on great content such as DV 4K Netflix content, and I set things the way I like. It's not like I'm a film maker and need a super-accurately calibrated monitor. Having done my share of photo editing on a calibrated wide-gamut (beautiful!) monitor, I'm pretty good at seeing and adjusting color. I'm so picky, I'm one of those here that returned my 65" OLED, rather than accept color issues like "pee stains" and a magenta cast to white screens. Color issues bug the heck out of me.
