“Deep fakery”
No such thing happened. During the two year restoration process among many other procedures, each of the original three-strip Technicolor nitrate film negatives (kept at a Warner Brother climate controlled 35F vault) were scanned at 8K 16-bit, composited them together and then applied a new color grain. The film was rescanned with the Lasergraphics Director 10K scanner. The restoration process peeled away decades of dust and dirt and used HDR to bring out colors and details that were in the film but not seen before. Examples, the rivet in Tin Man’s nose or freckles on Dorthy’s face.
