No, white is not white, when it is dim and contains elements of gray.
White definition - White is a color, the perception which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in nearly equal amounts and with high brightness compared to the surroundings. A white visual stimulation will be void of hue and grayness.
Second that BS about the human eye doing the ABL for you.Obviously if I can notice the ABL working then my eye is not doing it.The human eye has a certain degree of iris adjustment from bright scenes to dark ones, but is so minute that it goes unnoticed. The moment it becomes a noticeable feature it's no longer something that can be appreciated. The whole point of watching a film is for the suspension of disbelief,if I can feel the screen making luminance adjustments then howcan I suspend my disbelief?
Anyways these are just my opinions, and it's obvious they will conflict with any Plasma aficionado. Like I said before, don't listen to anyone. Everyone is biased, check for yourself.

A: I own an LCD TV and it has been my primary gaming/TV screen for the last three years (besides the last 8 years of using LCD's for my computers), but I like to educate myself on the technology I use thoroughly.B: What you're witnessing is because, as I said, you're throwing it into an artificial situation - increasing the ambient brightness of where you're watching the television. I predicted as much the instant you described your problem, because I know how it works and I know what causes the issue.
This has been known for years. If you're in your natural viewing environment, which on average is *not* a room with the sun directly facing you through gigantic windows, then yes - your eyes adjust to a given average level of light, and a sudden flash of brightness will cause your pupils to quickly contract. This is why police officers shine flashlights in your eyes at traffic stops, to force your pupils to contract as they should normally. It's what HDR in video games is supposed to simulate with the sudden light blowout followed by dimming to 'normal' levels - the sudden 'all white' being counteracted by our eyes reacting within a second or so to dim everything we see to where we can resolve details normally again. This is all pretty common stuff, and is something we're taught in elementary school, as I mentioned. Or at least I was.
All that is just explaining to all of the other users commenting and wondering why they don't notice this thing you're talking about - unless you specifically put the screen in a bright enough environment to cause your eyes to remain as if you're outdoors in full sunlight, you won't notice. This is also why it's been pretty common knowledge that in a store is generally a horrible place to 'test' a TV versus seeing it in your individual viewing environment.
Honestly, try taking those comments to avsforum if you're that serious, where there are plenty of people equipped with the past decade of talking about this to correct any other misconceptions you have. I just don't like people going off half-cocked and giving incomplete advice to others. The ABL only comes into effect if you're in an extremely bright room, which, as I mentioned and was able to predict from your related story, it so happens you are. And that's why there's always been the blanket 'if you're in a bright room get an LCD, period' advice for as long as I can remember.
It's easy to make noise about most LCD's almost all having off-axis contrast shifts in the central region of the screen because they use VA panels. Hey, it's there, but it's just how VA panels work, and it's the tradeoff you take to get better contrast out of an LCD! But it's also something 99.99% of users won't notice, so you don't see people running around trying to frighten others who don't know any better and wouldn't notice anyway.
