Are you sure there is no dynamic compression in the DD-mix?
Are the volume levels identical?
Is the DD-mix limited in bitrate (384/448) or does it use the full 640kbit/s potential?

If you want a comparison of codec audio quality only, try encoding your own DD-mix from the HD-audio stream, considering all the factors above.
Even then, you cannot be sure in case of AC-3, because people claim that the original, commercial encoder is superior to those available freely...
Blade Runner is just one example. Let's not derail this thread too much, but I can assure you, that once you go HD audio, you'll never want to go back, ever. And why should that surprise anyone?! A typical DTS-MA/TrueHD track is often larger in size than an entire DVD! With bitrates around 10x higher as regular DTS, the superiority of HD audio is a no-brainer, far as I'm concerned.
