Malus sylvestris , possibly. I may be incorrect given I haven't examined the sample or seen the tree.
There are a lot of ornamental cultivars being developed by the horticultural industry now that they can register the forms under Plant Variety Right laws which give them entitlement to royalties for every plant sold.
My guess is it is a form of “malus” (apple family), it has the tell tail smooth lamina on the top of the leaf and the semi pubescent underside. “Pyrus” (pears) tend to have smooth lamina on both sides, prominent lenticels and zigzag appearance of the twigs between leaf nodes and the fruiting spurs can be quite sharp like a thorn. “Sorbus”(crab apples) fruit is round in groups and have compound leaves.
Apples and pears are closely related and no doubt someone is at work trying to make a Frankenstein Pear X apple as we speak which will produce its own insecticide to kill codling moth.
I attached some web pages FYI.
