Hey Frank, We had a F65 ACES project last year and after a few tests with Colorworks to match our pipeline (DaVinci) to theirs (Baselight), we went with Sony's RAW Viewer for the conversion because DaVinci was yielding a saturation shift on the reds in the conversion that didn't happen in Baselight. After some digging we concluded that DaVinci was using an old IDT that wasn't recommended by Sony, so we stuck with RAW Viewer which was using the same IDT present in Baselight.
The conversion in Sony's RAW Viewer was done using the Color set to ACES, Viewer Settings to RRTODT_sRGB (v011 at that time), export format set to OpenEXR 16bit and the Bake option set to ACES/Linear. Nothing esoteric. Perhaps this low saturation you're seeing is due to the F65 gamut to ACES gamut. Because for what I remember the converted files did look duller than linear files with a smaller source gamut once you look at them in their linear form. Once you apply a Rec.709 RRT does the saturation look "normal" or "match" the same material converted to Rec.709 in the RAW Viewer directly?
