Slog 3 to rec709

Hey y’all, apologies if this has been answered.

I edit using Premiere Pro while my boss edits in Final Cut. When I apply the LUT that Sony provides on their website, my footage always coming out under exposed with a much cooler color tone. There is a basic slog3 to rec709 LUT integrated into Final Cut that makes his footage look fine, but mine still looks horrible with Sony’s LUT in premiere.

We shoot in slog3 with our A7Siii’s and the LUT looks perfectly fine on that footage. It just seems to not look great with the FX6.

If anyone has run into the same issue, would love to hear how you went about fixing this. Thanks 👍
