Comment (by fmnijk):

 The EXR file is gbrapf16le.

 Why when using libx264, ffmpeg automatically converts the input to YUV
 (yuv444p10le) and applies the correct color space (bt709), but when using
 NVENC, ffmpeg doesn't automatically perform this conversion? Is this an
 intentional difference in behavior between encoders, or should ffmpeg also
 handle this conversion automatically when using NVENC?

 I noticed in the debug logs that with libx264, the scale filter converts
 from gbrapf16le to yuv444p10le with bt709 color space, while with NVENC
 without explicit format conversion, the output ends up with bt470bg color
 space despite specifying bt709.
