Comment (by jb_alvarado):

 I have compare them in After Effects. But in my office we figure something
 out and maybe it is the same problem:
 We have files from Cameras how is compressed in XDCAM and it comes in mp4
 containers. blackmagic Davinci can not open this mp4 files, so I copy the
 video and andio lines from the mp4 to mov with ffmpeg:
 ffmpeg -i xdcam.mp4 -c copy xdcam.mov

 When I compare the new file in Adobe Premiere, I have the same color shift
 like with DNxHD. When I convert the mp4 to prores with media encoder and
 compare this with the xdcam.mov in Davinci the colors are ok.

 So maybe there is only a problem with the metadata?!
