Time to… resurrect (pun intended) this thread!
I captured the DTS LD (that “seems” to be different from the THX AC3 one), and compared it to BD.
Conclusions: LD has richer, punchy colors, with golden skin tones, while BD has duller ones, but natural skin tones; LD has more contrast, a bit more details in the shadows, a slightly increased sharpness. LD has more image on both sides, but less on the bottom, and also misses a single frame; this, along with the fact the image, even if correctly resized, doesn’t match with the BD due to some image aberrations (stretch and rotation) should mean they used completely different masters.
All these clues may lead to think that the master used for the DTS LD is indeed a silver retention processed print (more info on previous posts). Last thing: BD has the infamous magenta blanket applied all over it, even on the Fox logo; just look at fire, explosions, light flashes, reflections on water etc.
