Yep, I get the same thing. I've never noticed. I quite like the rendering from the Aali driver when comparing them though. The others seem too dark and you lose some detail.
Yeah, for the videos like the intro can be fine, but it's a bit jarring when a video is used to "move" the background and then the lighting changes quite a bit (Cloud looking at the reactor or the explosion to open the passage before Avalanche splitting up, for example).
