But how often did manufacturers do this? It seems like a wasted effort to claim something is less than it really is, considering how manufacturers like to lie about things and sell them as more than they really are.

The set you describe sounds like my first digital TV - Sylvania 6427GFF (actually a Funai product). In fact, the set in your icon looks like one. Mine sits unused in my daughter's bedroom.
I believe that its display/scanning system is limited to the 15750 (15734.nnn) line rate set by the needs of its flyback transformer. Flybacks are reasonant to a particular frequency. If the line rate were to be vastly different, the flyback could overheat.
Publications often made mention of EDTV as a format, for years between the earliest planning agreements (
Grand Alliance) and the introduction of the first DTV products, more than a decade later ($5,000 plasma sets and Voom satellite HD service), but, once DTV sets actually became avaiable to the public, EDTV somehow never showed up to the party.
