This is the first TV and the first time that I've never had any complaints about the way anything has looked. If something ever looks bad, it's due to the blu having a poor transfer (Image's Hellraiser 2 and Hills Have Eyes or Echo Bridge's Halloween H20 for example). No complaints. It makes everything look exactly how I want it to. But if I can make it even better with the advanced setting calibration then I'm certainly not opposed to that. I hear that you can really mess your TV up fooling with the advanced settings if you don't know what you're doing..
The really advanced color/gamma settings are very, very difficult to do at home (color wheels and your eyes really aren't up to the task as opposed to handheld sensors that pros use).
