This information comes from the card issuer directly, after the transaction has completed. It usually requires the mobile banking app to be installed.
The wallet app has a way to get the information, but it’s not from the tap itself. The tap interaction is not able to provide this information back to the phone (because the transaction auth happens long after the tap interaction completes).
Taps are designed to work with fully offline devices (which is why you can tap a plastic card, it is powered by the card terminal for the duration of the tap only, and requires no online interaction)

except of course it fucking doesn’t, I don’t have Chase or Amex apps on my phone… and yet my transactions are on my phone and watch and in a list inside my “wallet” and probably in the phone settings somewhere as well :)
