Good to hear.
Remember the setting could be off for different inputs on the TV, so you may not notice it because it's not on. Check that first.
However, I have noticed that when watching normal TV I can see it more (irritatingly so) when watching US shows (I'm in Australia). This does sound strange as every show comes over the air the same way I assume. Maybe its just coincidence and it shows up more on certain shows.
Right now I've just turned it off on all inputs. I think it needs improving as the bad effects it produces are unwatchable and the times when its good are not worth it for how irritating it can be!
