I tend to take a more expansive view of what is urban, as do most Americans in their daily lives. There are significant street facing developments fronting corridors throughout the distance between downtown and the Domain, and that isn't to speak of what is currently built at the Domain itself nor what it is in the pipeline for the immediate vicinity. This area is increasingly urban and poised to be more so in the immediate and medium-term future.

Yes, some (not all) of those neighborhoods in between downtown and the Domain are filled with single-family homes, but they are increasingly in a "walkable" setting because of that infill development along the corridors.

One other point: The Spurs stadium isn't, by your definition, in the urban core either.
