What about lossless audio on Blu-Ray?

There is even an AES recommendation on how to structure so you don't need
a screen to find tracks:

AES-21id-2011 (r2017): AES Information Document for audio-file transfer
and exchange - Screen-less navigation for high-resolution audio on Blu-ray
   Printing Date: 2017-05-01
   Publication History: Pub. 2011; Reaffirmed 2017
   Abstract: High-resolution audio, presented as uncompressed LPCM, has
been waiting for a suitable transport format for some time. The Blu-ray
Disc (BD) format offers such a transport and supports the necessary
linear and lossless codecs as part of its basic specification. While
many BD players can be found in home theatre and games environments,
there are some issues that need to be addressed before they can be
introduced into a hi-fi environment that does not have a screen to
present visual menus for audio stream setup and track selection. This
recommended method specifies a structure for authoring a BD ROM to
enable playback in screen-less consumer systems, and to provide simple
track selection from the remote control.
