 No, it is listenable, usually. Except for Dolby demo disk of March 2018.
 It has Atmos EAC3 sound without independent ac3 track (that track is
 present though but decodes to speach that says that this is not an atmos
 track):


 {{{
 [eac3 @ 000001320d0f4480] Ignoring dependent frame without independent
 frame.
 }}}

 and one more Ac3 track inside TrueHD that is also just speach.
