Comment (by spookybathtub):

 With the recent patch, 3D LUT application is more accurate, but still
 slightly wrong.  I'm comparing against DaVinci Resolve.  I start with a
 ProRes 444 file, apply the same LUT in both tools, and convert to YUV 422
 10b (v210).  The ffmpeg result is slightly more yellow.  Attached are
 screen grabs of a vectorscope and waveform, which show the difference.
