Sorry for the late reply. Visual iconic memory, I'm not sure. I would say I can't consciously visualise this way. My aphantasia is deep in the sense that it also covers other modalities. I can't recall the smell or sounds. Neither any smell or sound automatically triggers my memories.

Thanks! This PP hypothesis is plausible but things are even more interesting as in aphantasia you can still have a dream with visual content. So it seems that voluntary access to imaginary visualisation is somehow denied when awake.

I would say...I have semantic knowledge of the shape but I don't "see" any shape. I know what it is. It's difficult to explain this phenomenology 🙂
