I would think that DTS has the same 10dB boost. The receiver makes the adjustment as the line signal doesn't have the extra 10dB of headroom above the other channels. This is just because LFE effects were designated to be much louder than the other channels. This is just my opinion, as I have not noticed a large difference in LFE volume between the two types of encoded soundtracks.
