If you go to the link I posted, you can easily back out of that into a menu that will pull up the 82842 manual.
It doesn't have the CC screen.
The only reason that I and gtgray are mentioning this is because you wanted frank advice.
The amount of light control to avoid reflections off the screen has been exaggerated by some. I have a TV with a glossy screen, and it's fine with a floorlamp well to the side. I just turn off lamps behind me.
With the CC screen the 82" is as bright and contrasty as the 73", which to me was always the sweet spot for DLPs. I was surprised by the impact that the CC screen made on the picture compared to the previous year's model.
I'm sure you'll be happy in any case.
