I'm surprised nobody did this yet, but here's a comparison of the comic con video recently released by LFL, which actually contains some footage straight from the shown video (not shot by a camera from a screen):

It seem like it is slightly tweaked (for the better actually) but nothing as drastic as the pictures on the official site. As this difference is very subtle and could be caused by recompression, I'd lean towards the Blus being unchanged from the 04 version or maybe just really slightly tweaked, like this picture shows. Either way, I'd bet my ass that it will be the 04 transfer on the Blus, as the 04 version is effectively a version of the films that doesn't exist in any other form, so a new scan would be the 97SE (if they used the altered negative) and not the George approved version.
