Just wanted to point out that all those tv's you're talking about are LCD with an RGB layout. Not a single one is AMOLED.
Technologically the SLCD2 should look better if it's properly calibrated. The reason is simple. Color gamut. The performance of the SLCD2 (and LCD in general) is more in line with the source material that we use on a daily basis. If you look at the color gamut that both technologies are capable of the AMOLED is way ahead, which means it's capable of displaying a wider range of colors, which should be a good thing. But for us it's not. The reason is simple. It's capable of displaying MORE colors than are actually being supplied to it, which it what causes the over-saturation. Because it's capable of displaying more colors, the ones that aren't supplied by the source still have to get used. So at the far ends of the spectrum colors get "crushed" and make things look over-saturated. This can't be easily fixed by calibration. It would take a source outputting those extra colors to actually fix the problem the right way.
In short, you wouldn't use a professional computer monitor designed for final print work to do web browsing with. Colors would be off, contrast would be off, white level and balance would be off. It just wouldn't be a good experience. Take that same monitor, and supply it with a source that can provide all the extra relevant information and it'll look amazing. This is basically what's happening with AMOLED in phones right now. It's capable of so much more, but because of that, performance leaves something to be desired.
LCD, by it's nature, is designed to work better with the "limited" colors provided by todays sources. If anybody wants a more detailed explanation please ask, and I'll try to explain more.
