Frank - yes Movie disables it apparently. People were having issues with wonky performance in certain low light scenes iirc in the 7100 thread...the on screen brightness (or, dimness) would fluctuate mid scene, even if what was on screen didn't really change. When I got my set I immediately entered Buzz' settings as a starting point and was very happy with the results so left them as is, in Movie. Between that and what I'd read about the inconsistent performance of the micro dimming I never tried to dial Standard in. Switching to Standard doesn't look so hot to me (obviously I'd have to change other settings) but maybe I'll give it a try.
Strikingmoose - WOW that clouding is horrible, especially in the first pic. The rub out seemed to help quite a bit though even that second pic is a fair bit worse than anything I see on mine. As for screws, etc. yes - some have speculated that it's a physical pressure point causing this kind of thing. Some, myself included, have resorted to loosening certain screws on the back of the set. I loosened my lower left corner screw as that's where I had the worst clouding as well as corner flashlighting. Seemed like it helped, though it wasn't that bad to begin with, and it may be placebo effect
As for panel lottery I think there is an aspect of this for every set at every size, even if all the panels for a given size set come off the same exact line. I bet even two sequentially produced panels could look quite different. The tolerances nowadays are so exacting in these thin sets that what are likely extremely small differences in fit and finish seem to produce quite a it of variability from set to set. Though I purchased at Amazon, some retailers like Robert Zohn at Value Electronics will actually pre-vet a set for you to make sure you get a good one if you opt for calibration services. This costs extra obviously
All that said the relatively minor clouding I had seems to have improved over time, almost as if the set loosens up over time. Again though, hard to say if that's just me getting used to it or of it really has improved. I'm very happy with the set overall.
