Pretty much exactly this. It also makes watching adaptations pretty tough since books give descriptions of characters, then you male up an idea of what they look like and the adaptations just screw it up (usually).

The recall is amazing when you can remember a “scene” by “playing it out”. I think it’s usually more so just a skill people pickup when they read a ton and not super unique. I read an absurd amount when I was young due to being effectively blind and not prescribed glasses till puberty
