They may be unappealing to you but you are obviously not Joe Six Pack consumer seeing how the dominant sales to consumers are favoring that thin form factor with no difficulty selling inventory. Displaysearch has predicted that 184 million panels will be sold this year globally with strong growth in LED and the consumers simply are not agreeing with you - if Samsung PQ matched up to your assertions then they would not hold onto number one status globally and often N. America.
Your opinion has more to do with marketing though. Of course PQ isn't always going to be a top priority. Part of the problem with LED is their extremely directional nature. No one has figured out to tame them yet. CCFL is diffuse and more forgiving.

I simply think arguing against LED is a losing argument!
According to CNet, their highest rated models in power consumption....
Samsung LN52B750 128.86 watts -- .11 watts/sq inch
Sony KDL-46W5100 110.55 watts -- .12 watts/sq inch
Samsung UN55B8500 123.99 watts -- .1 watts/sq inch
LG 47LH90 107.16 watts -- .11 watts/sq inch
Samsung UN46B7000 93.02 watts -- .1 watts/sq inch

Off angle perhaps if you have a long distance viewing situation but if your panel is within THX standards for HD - you get immersion - SIZE within the proper seating distance means you have no off angles unless your sitting adjacent to the sides of the panels which would be foolish. Yes, some LED's have more noticeable drop-off's but that should evolve with the technology. Perhaps if your staring at a 32" weenie tv at ten feet but 55" - 70" at ten feet with 1080P should not be a problem. Not saying your wrong for you but obviously Consumers don't agree with you and your assertions.
BTW --- Per CNET Tables the Sharp 46" 700U LED is using same or less energy than the best CCFL 32" LCD panels and so Sharp LED is pretty much leading in the cost per inch. A 46" Panny plasma energy costs calibrated are about 400% more. Sharp 46" @$13.83 --- Plasma 46" @$60.69
Yes, the larger the edge-lit display the more difficult to uniformly diffuse light. The average LED LCD I'm seeing have horrible uniformity and off-angle viewing. The LED LCD on the market appear as if they have overdriven gamma levels. The top of the line 8500 has overdriven bluish blacks. Current LEDs themselves are also too large to ever come close to representing the resolution of 2.1 million pixels that comprise 1080p. Maybe in a few more years they will perfect LED LCD.
As for these fundamental (and unappealing to me) problems with Samsung's LED LCD, according to CNet:
"As much as local dimming helps, it's important to note that the number of LED elements behind the LCD screen still can't come close to matching the number of pixels in the LCD itself (1,920x1,080, or roughly 2.1 million), so the dimming isn't as local as it could be. Some of the elements remain lit in "black" areas, for example, which can produce visible "blooming" onscreen."
"We also noticed some uniformity issues, primarily in dark scenes as well, that are probably caused by the edge-lit LED system."
As for uniformity and off-angle viewing...
"The biggest weakness of LED-based LCDs comes in the arena of off-angle viewing, and the 8500 follows suit. When we moved just one couch cushion to either side, the blacks lightened considerably, becoming brighter, more washed-out, and less realistic, and taking the rest of the image quality down with them.
Even when in the sweet spot, simply hard leaning to either side caused the far edge of the screen, especially letterbox bars and other dark areas, to lighten noticeably (we were seated about 9 feet from the 55-inch model, so seating distances that are farther away will shorten the angle and lessen this issue). Blooming also became significantly more obvious from off-angle, and a bluer tinge crept into the dark areas. Dark scenes and low ambient lighting make the washout and increased blooming more obvious, but the falloff was still visible in brighter scenes and lighting. The 8500 seemed to suffer from this issue worse than other LCDs in our subjective comparison, but again that's most likely because its black levels were deeper than the others to begin with."
"The Samsung UNB7000 exhibited worse uniformity across the screen than the other flat-panel displays in our comparison--although it was better than the edge-lit Sony's KLV-40ZX1M. We noticed a brighter area along the bottom-left of the screen, as well as in the corners, that showed up in letterbox bars and darker scenes, such as the star field behind the opening credits, the interior of Keanu's tent and the dark lecture hall in Chapter 3. We also noticed that in brighter, flat fields such as the all-white of alien ball in Chapter 5, the left side of the screen appeared slightly darker than the rest.
In gray fields (from 10-70 IRE on our Sencore test pattern generator), we noticed more brightness variations across the screen, including a darker area across the top and subtle brighter splotches elsewhere. We didn't notice these variations much during program material, but they were more noticeable in test patterns than on any of the other displays in our test. It's worth noting that these issues can vary more than others from review sample to review sample.
When seen from off-angle, the UNB7000 also looked worse than any of the other displays in our comparison. Dark areas quickly washed out and became bluer, while brightness variations intensified, as we moved to either side of the sweet spot in the middle of the couch. The UNB7000 did seem to preserve its vertical viewing angle a bit better than the Sony or the Samsung A950, but both beat the UNB7000 in horizontal viewing angle."
