That's not the case here, TWOK on blu ray is all over the place, it seems they didn't do any color grading at all.Also, TWOK on blue ray has an ugly, blue look. I actually prefer the director's edition DVD
Yes unfortunately someone convinced Nick Meyer to sign off on the re-grading of the color into the popular steely blue/teal palette that pretty much all new movies use, it's really sickening...

Not sure what you're referring to, but the steely blue tint is all over the movie.
