Comment (by mirh):

 The color matrix I meant, whatever the player uses to convert YUV back to
 RGB.

 As I said thrice by now, you have ffmpeg that converts RGB data with the
 bt601 color space, but playback (without flags telling otherwise) will use
 bt709 above a certain resolution.

 This is not right, and it should be pretty evident to anybody that just
 tried the simple command in the first post. Please stop to wander on other
 bugs that may or may not exist tangentially to this.
