I'd say that the kind of content likely to produce visible banding has been well documented on this thread-and what I've read is consistent with what I see on mine. AFAIK blue or green color, as in blue sky or soccer field, will tend to bring it out. Combine that with a panning shot and/or motion in some of the content and it is more likely to be evident. (Let's refer to that for the moment as "banding-prone content")
AFAIK the extent of banding appears to vary considerably panel-to-panel. On the best 65" panels, it is barely noticable/minimal even with "banding-prone content". With the worst panels, it is very distracting with "banding-prone content" and may well be evident on other content.

Just 65s. Well documented in this thread so you can go back and read and make a decision.

Thanks for clarifying. Your pics and your posting your experience is much appreciated.
Personally I don't think we have enough data to support the conclusion that they've addressed the QC issues and that the newer build dates are improved irt panel quality, but it would be nice if that turned out to be the case.

I do think flashlighting and clouding have been improved with the latest builds as I don't see as many complaints from newer owners compared to earlier owners. Just disappointing that banding is still present albeit minimal.

Some people don't even realize there is any banding there. sometimes I have to point out banding to some, and they say, oh I thought that was the content doing that. If your spoiled with Plasma Uniformity, then move to a edge lit LED, Banding will stick out like a sore thumb on certain content. I like to tell people when making a buying decision to go into it knowing the advantages and disadvantages to each tech. Go into a LED knowing there is going to be some banding and you will be ok. Go into Plasma knowing you will get temporary IR, and you will be fine. Why I tell people no TV technology is perfect and if you go into it knowing what to expect, your all good.
There is no 100% perfect uniform edge lit LED. There is no Plasma that is 100% prone to IR. I think some people just have unrealistic expectations.
I'm happy with my 65" ES8000 with light banding. Its what I expect from a Edge lit LED.

No clouding. No flash lighting. No banding. Excellent off-axis viewing. Deep, deep blacks. Eye-popping, crystal clear 3D. The 60" version of the ES8000 is the real deal! As far as I know, the 60" version is the only one that uses a Sharp (Japanese) panel, compared to the Chinese and Korean panels used in the other sized ES8000 models. I'm not saying that's what makes the difference, but I am saying that IMO, there is a HUGE difference between the 60 and 65" models I had in my home.
It took me a while (plus multiple TVs) to get there, but thanks to Best Buy and their excellent return policy, I am one hundred and ten percent happy with my UN60ES8000 purchase. This model seems to be the one that hits the (size & performance) sweet spot in the ES8000 line.
As always, YMMV, but I think you'll be hard-pressed to find a better overall performing LED of this size at this price-point.

If you have a 65, banding is noticeable on any content, not just slides. It's a limitation of the design. If you don't see it, you are fortunate but it is still there. You just may not be as sensitive to it in the same way others aren't bothered or don't notice buzzing on plasma or dead pixels, etc.

See sound of minds post, he explains it better... But yes, banding is not limited to viewing slides but can be seen while viewing a bluray, cable, etc if the right combo if light/dark, panning etc. Not sure what you are talking about especially since you seem so knowledgeable from previous posts.

That does not explain why we see 5 or 6 lines of vertical banding.
Should there not just be one band where the film is joined together, why so many.
If 60" and below are in one piece, surely 65" should be just 2 pieces and then just one band where thery join ?

I will try and explain why there is multiple band lines in film. This may take awhile, but I will try and condense.

This is a film line similar to those that make the layers for the LED/LCD arrays used in our televisions. The horizontal stainless looking item with the multiple holes in it is the die, which takes the melted plastic and spreads it out across the width of the die, lets say 50" wide, and 1/4" thick. There is an opening along the entire width of the die where melted plastic is squeezed out in a long line-the length of this opening determines how wide the melted film is.

The die in this photo is on the far right. The melted plastic coming out of the die is squeezed between two textured rolls, which are cooled well below the melting point of the plastic. The melted plastic is solidified within an 1/8" after contacting the compressed rolls. This quick solidification causes various stress in the film, all the way across the entire width. These rolls may be turning anywhere from 5 to 500 feet per minute, depending on what you are making.
OK, anone ever measured a piece of steel or aluminum with a micrometer? Its not dead even in thickness all the way across the width. Same thing with film-they have a thickness tolerance of maybe +- 5% across the width. So film that is 0.030" thick may actually be .0285" to .0315" thick. Say I take measurements of the film thickness across the width with a micrometer after the film is finished. Here are my measurements, across the width--0.0287, 0.0296, 0.0313, 0.0289, 0.0312, 0.0290. The film meets specification because its +-5%, but is really not level.
Remember back in the previous paragraph when I told you I put stress in the film because I squeezed it between two rolls, and cooled it from a liquid to a solid very quickly? Now, the higher measurements have greater stresses in them than the lower micrometer measurements. I just measured 5 points across the film, but now imagine the highs as hills and the low measurements as valleys across the width of the film, going down the length of the film like little straight rivers. Remember, I've squeezed this film between two rolls, so the hills (high points) have much more stress in them than the valleys (low points). When you backlight or edge light the film in the array, these lows or highs looks like a band down the length of the film. I'm not sure if the banding is caused by a low area, or a high area.
If, like on the 65" sets, they splice two pieces of film together, you end up with banding across the entire web.
Either Samsung is having an issue when they make the 65"-it's process related, or the film they use for the 60" and below is of a litter better quality, or a little easier to keep the high and low stress out of it during its initial manufacture. I bet their technology department has this as their Number 1 problem to solve.
Samsung has to be losing money on the 65", another reason the amount of banding they seem to be allowing is increasing--the bottom line is they are doing the best they can with their present technology.
