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.
