I really could not understand why I’ve been getting such inconsistent results. I calibrated the latest version of the algorithm on this frame:

As far as I can tell, it looks just fine. When I apply the correction to other frames, I’ve been getting color shifts, that were mostly yellow/green, but also blue. However, when I examined the raw scan I noticed the relatively large differences in hue, brightness, and saturation between these two frames, that are only a few shots apart:

These inconsistencies are most likely caused by the scanning process, as poita’s scan looks much cleaner, an much more consistent.

The print appears to have a different source spliced in at this point, it is completely different colour wise suddenly in my scans as well. The Spanish print is a dog’s breakfast really.

I like the idea of being able to use part of a frame as the correction source, Artoo is especially useful for this.
