You are singing my song. Think about the history of the "horse race" between LCD and plasma. Plasma had a big headstart in regards to size. LCD had to invest tons of money to develop "wafer steppers" large enough to make cost-effective 42" LCDs. Once they could catch up to plasma, plasma then had to "attack" LCDs on "implied" weaknesses. Since LCDs have a backlight on all the time, it needs the polarizers et al, to block the light to make black. Since the industry tests contrast (white level compared to black level) in a darkroom, the LCD has a reasonable low contrast ratio (500 nits divided by about .25/.5 nits). Since plasmas emit NO LIGHT for black, the nit rating for black is essentially ZERO. How many ZEROS go into 500 nits. You can see that if the marketplace likes to compare numbers, tested this way, Plasmas have a much better contrast ratio. Is it fair? Legitimate? Real world? Nope.... but numbers are numbers.
In reality, the internal structure of the plasma is what is reflective. Sure the front surface reflects but it is the internal reflections that really corrupt the colors in a lit room. If you want good plasma, turn off the lights.
