Erich, all of what you say is correct and spot on - especially in regards to the ‘new blue-ish color grade’.
Yet I’m a little surprised nobody has taken more of an interest in this - even to if just to ask the OP whether there is a pre-new colour grade version available. Or to request some short video clips to demonstrate quality etc.
👍
Edit: I see DrunkenMaster442 has since edited the OP to include this information for his project…
I am currently Re Grading the restoration to better fit the 2011 Blu Ray release.
