Sony A7siii - Weird color in Slog2 at 12800 ISO

[jqa1191]

I am shooting at Slog2 in S-gamut3.cine at 12800. With this photo attached, there is a weird inverted color look on his neck. I tried many ways to fix it in post, but nothing is working. It's god awful looking! There are other examples of this with the same person in different shoots. Is there something wrong about using such a high ISO at slog2? Even though this is at the "Dual-ISO"?

This is a consequence of a unique "Color Science from Sony" and not enough stream to compress all video data.

Only writing to RAW will solve this. But many movie cameras don't even work with this high ISO.
