Sorry to bump this after so long, but I noticed something interesting. When this clip appears in "ILM: Creating the Impossible," the part with the blade on black is blue...

...but the final comp has it with the aqua/seafoam tinge (like in the above screenshots from TMoSW).

When the test footage is shown in TMoSW, the color balance of these two clips match. In ILM:CtO, they don't. Is this just some digital monkeying by the makers of this doc?

I wish there were a 70mm film cell, or a snapshot of this scene from the Senator screening...
