Some CD's were mastered with pre-emphasis (vaguely similar to the RIAA curve on vinyl) and something in the bitstream on those discs tells the player that they need to apply de-emphasis to compensate. If the CD player doesn't do this the CD will sound too "bright". If the de-emphasis flag in the bitstream gets lost...or the DAC doesn't respond to it...then the file will sound too bright. This pre-emphasis is pretty rare...IMHO it was mostly early classical discs... I'm not sure anyone uses it anymore?
