I'm having trouble operationalizing the "blind mind's eye" concept. Catmull's brain knows what a sphere is, and my brain knows what a sphere is, and we can both describe the experience of seeing a sphere, so we both know what one "looks like."
Compare this to the phenomenon of "face blindness." My friends who suffer from this genuinely cannot describe what makes Angela Merkel's face (for instance) different from others because they lack the facility to remember it. But I can, because I don't have face blindness: Merkel's face is wrinkled, craggy even, with crows feet that resemble smile lines.

What can I do that an aphantasia sufferer cannot?
