I was thinking more like those "alpha channel" screen calibrators that lots of games had. Adjust the contrast until the top bar looks to be the same brightness as the bottom bar, then you get another screen where you adjust the brightness until a gray bar is just barely visible. But yah film modes help with this as long as all the fancy stuff can be disabled. OTOH, I actually like having some basic motion/frame interpolation enabled, because 24FPS drives me almost as crazy as bad 3:2 pull down encoded (or not encoded) streams where slow motion pans/etc are jerky. I guess some of these TV's have a black frame insertion mode (or its part of the film mode) where it drops black frames between 24 FPS content and that helps too.
