I agree with Neverar. Dre, I'm certain that it was unintentional, but your Star Wars images there are literally the exact same url. Here's the comparison, at least using the images you had a couple days ago:

You can see that it gives the same general impression and tones. But it's lacking the specifics and looks more homogeneous overall. The shadows look a bit funky, too. If you look at shots 1 and 4, I think there's really no competition. The specific match looks like a technicolor print. The non-specific looks like it's in the ballpark, but not right.
The predictive ability is really neat that it even works as well as it does. A great proof of concept and I'm sure there will be cases where it's useful because of limited resources being available. Now, I'm not suggesting it needs to be frame by frame, but probably shot by shot or as new elements enter a shot. Applying one ref over a wide range of frames seems like it would be risky for introducing artifacts and incorrect color.
edit: I am curious if your second Indiana example WOWOW and Match might be identical images. It seems the actual WOWOW might be missing.
I replaced the duplicate images for both the Star Wars and Indy examples. I also switched to another image hosting site, because screenshotcomparison can be frustratingly unstable at times.
You actually used the C3PO/Owen image that did not have the correct cropping, so the colors came out wrong. The one that's in the example was the correct one, posted after neverar great noticed some problems. The correct prediction is very close.
Let me eleborate a bit in the next posts...
