But I would like to say this: Among many other possible causes, banding or posterization CAN occur as a result of compression or improper encoding in the source. Low bit rate compression will introduce it very noticeably, YouTube is a perfect example. And as far as media providers go, the bandwidth per program varies.
Digital video inherently has banding, the only solution is to use enough bits so that the gradations are "smooth" to the viewer. Obviously, compression is throwing some of these bits away. And given gamma, banding is going to be more noticeable at some brightness levels than others...the same value is applied to wider swathe of the gamut at different locations on the curve. You could consider the gamma adjustment to be "controlled banding".
So to discern if banding is introduced by the set you must, first and foremost, be viewing source material that is encoded properly and without extreme compression. My opinion would be that any source more compressed than a studio released BD would not be suitable. Actually, the only source I would use is a gamut pattern of some sort from a calibration BD. Whether or not it exhibits banding on one set vs another is irrelevant unless you know, quite reasonably, that the source contained none.
And if a source was known to contain banding, but the set's processing reduced it, I would be unhappy because the set is adding information to those areas that is not contained in the source.
So it is a possibility that you are see the banding because you now have a set that is more accurate at delivering the information as contained in the source to your eye/brain than many of its competitors.
I have not seen any banding when viewing grey or color ramps from the DVE BD. I have not seen it when viewing digital photos from my computer set at 32bit color, or HD home videos from my Panasonic TM300. But I see it all over the place on DishNetwork programming. Again, I have not compared 60Hz vs 96Hz for 24Hz content.
Just my 2¢.
