It does seem obviously to be a spectrum. I only realised that I have some degree of aphantasia when I read an article on it.
I think there's also an element of things being "faint" in your mind's eye. For example, there's a McDonald's and horse racetrack that I drive by every day on my way to work. I can sort of visualise some constituent parts, but there are no details and there's no overall picture.
I also don't know how much of the visualisation is just me recalling (in abstract) what is there, since I am very familiar with it.
