The default UI uses hidden back-end implementations for this. There is nothing special defined in UI that reads that value from the selected unit (and currently there is no special frame that does this, although other aspects like life/shields/energy/behaviors can be added separately now).
The first solution idea might be animations, but since you need to show the InfoPaneUnit frame, you would need to hide its other elements to only show the attribute labels. The problem with this is, that it might be impossible to properly detect. It can be done via tricks with a unit selection panel, but that is buggy with observers and AI and I don't think Blizzard fixed that issue (I ran into that in some of my GameHeart UI versions).
But this is still possible with only using UI. But it needs to use an old dirty trick of mine. You can create a new InfoPanel within the InfoPanel's pages and hide the elements you don't want to see.
Usually, you cannot create new InfoPanels as they are flagged as Blizzard-only. But you can create multiple new info panels via using "Frame" as the type instead of "InfoPanel" and then applying the template to that Frame.
The resulting info panel will not work 100% (or at least it used to, no idea what changed over the last 2+ years).
