All of this will be invisible to consumers, just as supporting competing Dolby TrueHD and DTS-HD MA is as easy as putting in a disc and pressing play. Since format recognition and decoding is done automatically, it doesn't matter how many competing formats there are. And if your receiver or pre-pro doesn't have a particular format decoder, it won't render a disc unplayable, since all 3 immersive formats are backwards compatible. You'll always get to hear the soundtrack, in the highest channel count your system supports.
Not that I disagree with you, but there is big difference between Atmos/Auro/DTS:X and the legacy formats, and it's the lack of a common, accepted and compatible speaker layout. You could switch easily between Dolby True-HD and DTS HD MA because the 7.1 speaker layout was exactly the same. Even if you had PLIIz or DSX, it was just speakers added to the standard 7.1 layout, using common locations (FH were absolutely compatible between PLIIz and DSX, for example).
The fact that height/top speakers are different in each immersive layout, and the fact that even if they could be used in the same position, there are limitations in the early implementations of these preventing from sharing an Audissey configuration between the formats simply because the speakers are not called the same, make the switch far from being as easy as you describe.
If they all agree on a common, compatible speakers placement, and if implementations then allow to switch easily between each format without having to chose between losing your calibration or losing a pair of heights or more, then I agree it becomes transparent for the user, like legacy formats are.
I certainly hope we'll get there (or that only one format will actually become the standard) but as you know, looking at the way we can switch between Atmos and Auro in the D&M implementation, we're not there yet
Of course if you're only talking about upmixing, that's different, but I'm talking about making the most of each native immersive soundtrack.
