I take it you're referring to UA's Japan flights, as codeshare doesn't have anything to do with it - that's just a matter of putting one carrier's flight number on a flight operated by another carrier. You can buy literally hundreds, if not thousands, of UA domestic flights as an NH codeshare.
But no, even on the Japan routes, UA did not serve the same meals as NH. That said, pre-covid, the UA meals served ex-TYO were pretty consistently the best that UA offered anywhere (though IMO nowhere near as good as what NH served).
