My understanding for the DTS on DVD (not sure of Blu-Ray so I won't even speculate on that) but the audio was completely remixed by DTS before being put on the discs, so it wasn't just an amplification or a re-encoding, but a full remix. Sure, the LFE seems a bit "louder," but I also find that the surround effects and overall ambiance seemed to be a bit better that DD. I have no idea how it would sound (or if the average human ear could tell the difference) if it was just "less compressed"...
Anyway, I like the DTS remixes.
