I'm not exactly sure how the standard works.  I know that they they
added A/72 to the ATSC standard, rather than calling it a new standard
(ATSCv2).  However perhaps when a television says ATSC compatible, its
really just saying its A/53 complaint?  I don't know.

But I do know that the US FCC has not adopted A/72... and uses A/53 as
the standard for broadcast television.  I suppose they could adopt
A/72 if they chose, but I suspect that it would be too costly?
