Clouding and flashlighting are inherent problems with lcd/led technology that have not gone away, much less decreased significantly, in recent years.
How much has PQ improved in high quality lcd/led panels since the inception of 1080p? I would say not at all, or only very slightly. There is greater consistency in the manufacturing of lcd, ie fewer dead pixels, but overall there is not any more information to be squeezed out of tv's.
4K and 48 fps films will improve the picture noticeably. Otherwise, we're mainly paying more money for thinness, light weight and marginally effective "smart" tv functions.
To a certain point I agree with everything you say.
I forgot to mention that my wife and I have another LCD TV in front of our treadmill that we've had for about 5 years. It's a 37" Viewsonic 136?x 72?, CFL unit that cost around $900. (That amount would buy a fantastic TV today.) It's been trouble-free. By today's standards, Its image quality is marginal, but it's perfect for playing whatever when we're on the treadmill. Blacks are grey, but whnen it's on we're more concerned with keeping our breath than image quality.
About 4 or 5 years ago I remember seeing a 65" Sharp 1080p TV at a local Costco. The price was $15,995. In short, I was not impressed with the image quality, but I'm sure the set was not calibrated to the best that it could be. The calibrators on this forum would be much more able to state how much improvement there has been in LCD image potential over the past years since the inception of good 1080p sources.
I went over to our daughter and son-in-law's home yesterday evening. In August of 2010 they bought a Samsung UN65C8000, which was at that time the top-of-the-line Samsung TV. I brought over some BDs that I had burned and wanted to test for playback on their Samsung BD and Sony PS3 players.
Well, to my eyes, that "old" set looked every bit as good as what I've seen in any showroom during the past couple of weeks. Yes, blacks are not perfect, but they're somewhat-to-significantly better than our 32" Aquos. Contrary to what purists like, I like the so-called "smooth motion" effect. We watched the beginning of "Battle of the Bulge" over the PS3. Seating distance was about 7 feet. I could not believe how fantastic the image, in every respect, we saw was. The interpolation that the TV must have been doing was, as far as I could tell, spot on. I was floored.
Every review I've read about the Elite TVs says that their full array, local dimming technology brings blacks to the plasma level. Maybe Sharp's upcoming 950s will be as good at a much lower price, but you are right that these, especially for everyday TV viewing, are only marginal improvements.
At our present seating distance of 12 feet, in order to see much improvement in a 4k, 48fps, display, we'd either have to reduce our seating distance pretty dramatically or get a display much larger than 65".
