Andrea, it appears that the screenshot you used to compare was from the UK Escape From New York BD, not the U.S. version. Those are night and day different. I'm not saying the color timing is correct or incorrect in either case. I'm just saying that particular HD capture was from UK not U.S. Here's the source:

Just scroll down to the screen shots and you'll see the U.S. captures appear third in the group shots. The UK BD is just a green mess. I don't know what those guys were thinking with that boosted contrast. That film is supposed to be dark. Now the U.S. BD screenshots may appear darker, but that is easily fixed by adjusting your display.
