From a paper on aphantasia I read a while ago I recall that the difference is about which brain functions you use. Spatial thinking vs. visual. The former works fine in aphantasia, the latter does not. As I understand it it's the difference between decomposing the barn into a cube and a prism, performing perspective projection on it, without the help of a ruler, and then rasterizing that into a 16x16 grid while also assigning colors while holding all that in your working memory at the same time and only being able appreciate it as an abstract 256-item long list of colors vs. having a finished and higher-fidelity result including grass and sky hallucinated by your visual system with little mental effort, allowing you to use the same downstream processing that you can also use when looking at the actual thing.
