In the end, I asked them to export an DNxHR 4:2:2 planar 12bit and I'm gonna upscale the chroma to 4:4:4 for the MJPEG2000 Cinema encode (Avisynth + ffmpeg and OpenDCP), while I'm gonna downscale the chroma to 4:2:0 planar and then dither everything down to 8bit with the Floyd-Steinber error diffusion for the Bluray release in H.264 (Avisynth + x264 + ffmpeg + Scenarist).
Thanks.
