I have also seen the dirty screen look on many different LCD screens (including some of the high end models from various brands). Dirty Screen Effect (?)
These anomalies are just part of the tech and for those that don't see them consider your selves lucky dawgs... because it's there (where it applies of course, as in the diamond pattern will not be there on an edge-lit set). Just as no-one can tell you if you'll see RBE with DLP, if you'll have motion issues with LCD, if you'll see the shimmer on inexpensive grey front projection screens or the screen texture on rear projection tv's, there is no way of knowing if you'll notice the diamond pattern or see the dirty screen effect (some will see these anomalies and some will not but they are all just part of the tech).
Anyone that claims they are viewing a perfect display are simply not seeing the inherent issues with whichever tech they are viewing (and they all have them in one form or another). The best we can do is see as many as we can and weigh the pros/cons. So please remember to never let anyone tell you that you will not
see any of the known anomalies on a particular display. Obviously suggesting that you should not see them because the majority do not appear to on a particular display is a logical suggestion (just never definitive until you see it for yourself).
How about this one... SDE on the 80" due to the pixel structure and someone sitting too close or possibly having great visual acuity. Screen Door Effect
*SDE is usually a term tossed about in the front projection forum but since the 80" is approaching front projection sizing and still 1080p it could very well apply.
