I'm absolutely not faulting you, Y_T - the red information in the transfer is just that screwed up.

Can someone help me with my knowledge on this - how much of the blu-ray redness is red damage/red shift now in the original damaged negative and how much is redness boosted in the color correction moves done by Lucasfilm.

It is all by Lucasfilm. They call it "George's vision".

EDIT:

Thought about another thing that shows it even more.

Harmy posted this re-timed 70mm frame in the color timing thread, which should look like the original technicolor version:

Here's the same from the blu-ray:
