Yes I do. For shits and giggles the other day I ran through the Xbone calibration tool. Pretty close to spot on other than the gradient blocks of white and black, I want to say it was the last two blocks that blended. Or my eyes are bad and I couldn't tell.
I do find some games will be a hair too dark or light at times, but my TV can switch between light and dark black levels that fix that. My method is to just throw in a vivid game of sorts and fiddlefuck the settings until it looks good. Colors pop and are accurate, blacks are black, sharpness isn't blurry, but not so sharp as to cause white aliased lines on all the edges.
