Someone else in this topic has a F4500 and a probe. The way he measured is slightly different ( he measured colour at 100% amplitude/100% saturation, whereas for best results I use 75/75, anyway, his settings for the CMS were virtually identical to what I got at 100/100, so i would say the panels are built in such a way that the difference between units is incredibly small. Before buying my TV I read a foreign review, (Bosnia I think) and it said that their F4500 review unit measured identically to their previous years E450 sample.
The main difference is my black level is amazingly good, I get 0.009 candela with black optimiser off or dark room, and 0.0068 with black optimiser auto.
The other guy got 0.013 on his F4500, I don't know if he used black optimiser or not, its a really good feature.
Dark room has a barely any better black level and cuts maximum light output a bit.
Bright room gives a max light output boost and might rise black level a bit.
Auto gives darker black and brighter white, I get 20000:1 on/off contrast as opposed to 15000:1 without.
From the limited amount I can find to read, it remaps 16-235 to 0-255 to give more graduations, and in dark areas instead of illuminating at the normal rate, it refreshes those areas at half the rate so they end up darker.
Going back to the measured 0.013 of the F4500, thats with a full black screen, on mine with a ANSI contrast pattern I still get a black of 0.014 and contrast ratio of 5500:1, my Sony PVM CRT (0.002 candela on/off black level) only has 7:1 ANSI contrast!
So with half the screen white I still get 0.014 candela black.
