The restoration had to make some different color moves because the layers were either gone or quickly going. They had to spend enormous amounts of time to color grade and match period decor to boot.

The new BD uses the old 2005 struck master with some tweaking.

Unfortunately, this was all handled with analog technology for the Harris-Katz restoration, and the color balance is far from the same as originally.

Actually though, the BD is from a new scan of the negative, digitally color corrected. It's arguably even more flawed than the previous 1996 restoration, color-wise. (Robert Harris attests to this.) The 2005 master would have looked terrible on BD though, for lack of detail in the scan.
