Although the BD does restore some shots that are digitally altered in the WOWOW such as the plane in the image above and the red ‘travelling line’ sequence. So given the choice between the two sources in terms of a single-pass colour correction, I would probably opt for the BD.
That being said, the BD has the digitally illuminated lamp in the ark-opening scene which is properly off in the WOWOW so a best-of-both approach would be amazing.
The BD has too many issues which can’t be fixed. Some things are too altered color wise or overexposed to the point of obliterating detail. The orange/teal color is inconsistently applied, sometimes to the point of erasing the original colors and some detail. The opening of the ark sequence in particular is recolored and overexposed beyond salvaging. It’s truly one of the worst examples of a famous scene being completely effed up. I can’t believe Spielberg ever approved it. The couple of re-composited shots you mentioned could be taken from the blu, but I would use wowow for everything else. And even that has a few problems. The only properly exposed official transfer of Raiders is the DVD, but there isn’t a good enough HD transfer of that available.
