Blu-ray arguably has better quality audio than is presently possible on DCP. DCP only allows LPCM audio, the maximum sampling rate is 96 kHz. Yet the maximum Blu-ray sampling rate is 192 kHz.
Most peoples ears can't tell a difference. 192 is better for *recording* the audio because it captures more details in the recording process, but once it's recorded downsampling it to 96 or even 48 will be virtually lossless.
