Are you sure your TV's brightness and contrast are calibrated properly? I have to turn my TV's brightness way up to see the line. This would also cause the grain in the logos to be more intrusive.

The flickering is there and I'm well aware of it and I don't know how or why it happened but it's only in a few shots (I can't recall any beyond those you mentioned) and would probably again be exaggerated by improperly set contrast.

EDIT: I don't see any flickering in the trash compactor scene, except for the red lit faces in two or three short shots (and that's a different issue from what Erik mentioned and is caused by using only the red channel for luma in the darkest areas). The rest is just grain.
