Goods points, You_Too. We had that discussion about the changes in colors for the Road Warrior Blu-ray. They scanned the negative which was cool/blue but the original release prints where warm/yellow exactly the same as the old DVD and LD. The release prints where chemically processed to be more yellow to give that desert feel. The cinematographer planned it that way and took great lengths to achieve that look. When WB went back to the negative, they simply scanned it and release it without trying to reproduce the original release print's look.
That's also what happened to Conan the Barbarian on blu-ray. It has the look of the negative, without the color timing that was done for the theatrical prints.

Speaking of laserdiscs and Cameron. Aliens is interesting. I have been capturing my old LDs lately. Trying to make backups in case my player finally bites it. When I watched my capture of Aliens (letterbox/theatrical), I expected it to look like the DVD. Nope. The DVD has a little more muted look in its colors. The LD is warmer and has more saturated colors. I actually kind of like the LD's colors better then the DVD's. Suffice to say the BD, DVD and that LD all look different.
LD's are interesting indeed. Sometimes when an LD release is very different and warmer in the colors than the usual home releases, it makes me think maybe they did that because of TVs not being calibrated back then, like some compensation for the otherwise cold look it would get when viewed. Of course that's just speculations but it would be interesting to know the truth about it.
Then of course, it could be that when some LD's were released, maybe they scanned the negative or some kind of pre-color timing print and accidentally "got rid of" the intended look.
