The only SE line that's still in there is Han's German "Yes, I bet you have.", which was re-recorded for the SE. As far as I know there weren't any other lines changed in the SE. So yes, the DTS track contains only theatrical lines, apart from Han's line to Greedo.
The rest of the remaining SE stuff is a sound effect here and there and some imperfect music or background sound transitions where I had to remove SE additions (and where EditDroid's 5.1 track didn't help fixing it).
That being said, the other three German tracks (GOUT, 1993, 1995) were ALL out of sync to each other AND Harmy's video track as well. I've edited them all to be as in-sync as possible to the video track, so I don't think it's noticable.
