The blu ray is miles better. I've been doing a/b comparisons in different sound formats. From streaming to blue ray. The stereo format seems to be the best way to listen to streaming. But there is no question the blu ray version is the way to go, it's high fidelity, i've found that dolby sounds the best, but Yamaha's AI is really good too. Going back and forth between dolby and AI and it's a tough call.
I started the a/b comparison to see the difference between blu ray and streaming, i've found that if both are played in stereo it's tough to hear the difference. But you select a decoder, the blu ray is an entire level all together.
