Tokyo Jungle? Wiki seems to indicate it got physical in Japan, so it's likely formatted right. Kinda strikes me as the kind of game that'd just suddenly get a switch version announced alongside an unexpected sequel, though - if not now, then at some point, on some future system.
Only other ones that come to mind are the unfinished swan (though that's also on ps4 storefront), and...maybe Strongbad's cool game for attractive people, since that one never got a physical like the Sam&Max games did on wii?
Tokyo Jungle already has a physical release for Ps3 in North America. It is on a disk with Sound Shapes and Fat Princess.
