The only dvd-audio I know of that had no on-screen operating system (actually, there's no video content of ANY kind present) is the Elvis Presley disc...and I sure wish more were authored that way.
I read years ago that a dvd-audio disc could be authored to play just like a CD, but the main reason given for not doing that is that since it is a dvd-based format i.e. video related, supposedly "everyone" expects to use their TV with them and that is how most are made. That is the dumbest thing I've ever heard as far as that format is concerned.
FYI for those unfamiliar with this format: many dvd-a discs
can be used without a TV, as long as you only want to listen to the multichannel tracks (setting the disc in the tray
and then pushing "play" FIRST will cause the disc to play like a CD). It's when you want to switch to stereo or another set of tracks is when things can get weird quick with many titles.
I'll be pissed if they screw this up again i.e. if the operating standards for the Blu-ray version are as disorganized. The "do it if it feels good" attitude was great for the 60s, but not for music format standards.
