Not to derail the thread, but I really liked the colors of Terminator Salvation and if I recall, they actually achieved those colors photo-chemically, not in digital grading.

And to get back on topic, Mike, I don't know if the color-space conversion has something to do with it, but in many of your videos, including this one, I feel like in your restoration the reds are a bit biased towards magenta/purple - in this example, the colors in the blu-ray are undeniably horrible, mainly due to over-saturation (yeah, the pink highlights are a thing to behold), but I just feel like the hue of the red stripe on the x-wing is closer a true red (albeit extremely boosted and over-saturated) on the BD.
