I cannot see the Dolby Atmos option in Mac Music app settings. Any idea why?

I'm having a MacBok Pro 13" 2020 M1.

According to the technical specs it is capable of playing Dolby Atmos.

According to this page all I have to do is activate it in Music app settings:

But I don't have this setting in preferences / playback. Only for video quality.

I cannot find any more information about Dolby Atmos anywhere on Apple website.

Has anyone an idea what is going on?
