Most of the time, no. Probably because as "standard" as sizes of appliances are- they also are not.
So the last thing you want a potential buyer worrying about is (1) looking at an empty appliance slot or (2) knowing the appliances are going and worrying if they can find something to perfectly fit in the same spot.
I mean also, because appliances usually stay.. it's kind of a problem for no one. Often times someone is selling a house to build a new one, they don't want to bring old appliances in a new build. Or if you are buying a pre-existing house, that will generally have the appliances etc.
Also, appliances have been subject to the same supersizing effect as many other things in the US, especially refrigerators. A kitchen built or last remodeled prior to the mid-2000s or so is likely going to have trouble finding a fridge that will fit properly because they've gotten so much larger.
Appliances wear out and need replaced and lots of property owners don’t regularly remodel, so there is a pretty big market for, and ready supply of, things like refrigerators that fit older houses. In a brick-and-mortar showroom, they won't be in the most prominent locations, but they also will often be fairly well priced for what they are because its a large and price-sensitive market segment.
