They just don’t have the data.
Look I got covid while wearing a mask. Infection was either at a grocery store. Or while walking at a park. Or while at a dog park. Or who knows.
How do you log that in your stats?

If you get a positive test, contact tracers may ask you where you went and who you interacted with. They then call those people and ask them to get a covid test. IF the contact tests positive, then rinse and repeat. [3]
If I live alone and only leave my house to grocery shop, it is pretty clear where I got covid. Similarly, if Bob had covid, I had dinner with Bob, and now I have covid, it is pretty safe to assume I got at dinner.
Anecdotally, I had a friend who tested positive and the contact tracer told them that they had likely contracted while it shopping at a big 5 several days earlier.
