For myself, I don't think I have aphantasia, unless it is something that can come and go. There are times where I daydream and experience vivid visions akin to psychedelic closed eye visuals (except actual visions, and not geometric patterns). Most of the time when I daydream, I can picture something in my head, but it doesn't have the depth and detail of what I experience when deep in thought.

I'm also not very much of a visual learner. I appreciate well written text to a graphic or diagram when trying to understand something new.

This was just my anecdata to backup your statement about self-reporting, and how any one individual can experience this vastly differently than the next person. I also think that phenomena like this is what is going to end up holding back artificial intelligence, as far as trying to map human mental processes on to computing. We have a long way towards understanding our own minds before we can fully conceptualize true artificial intelligence (although that doesn't make current AI not useful).
