La La Land 这个例子比较特别,因为 4K 与 2K 版的蓝光碟也提供 24-Bit/48 kHz 的 Dolby Atmos 音轨,而且能够单独播放歌曲部分:

Song Selection – Allows you to watch the individual songs from the film.

Song Selection allows quick access to the film's tunes, and also offers a Play All option (48:52).
当然那是 9.1.6 声道的音轨,幸好 Dolby Reference Player 配上 Music Media Helper 就可以把它渲染生成两声道 WAV 文件:

老外的 MMH 则需要先安装 .NET Desktop Runtime:

通常 Atmos 的动态范围也比较好,黑胶的 DR 也不错,但是 CD 跟流媒体的 DR 就相对逊色了一点:
