For me imaginary input has less details and exists in a separate plane, and it never mixed up with real senses, in the sence that I always know which is which and to my knowledge I've never mixed them up when awake (only in sleep).

Visualizations are "ghostly", have few details, like 0.1 - 10% of what I usually see. Detail level depends on amount of attention allocated to internal imagery. Picture is always moving, changing, in flow. It takes considerable effort to pin a scene and stabilize it though it increases resolution. I've asked around and some people report having sequence of static, very high-resolution, almost real life quality pictures, either from real experience or synthesized. And images flip, replacing one another. Other people say that they have very fast low-res flowing "movies" like me, often consisting of several independent streams in different "parts" of awareness, typically with only one if focus. It's not that imaginary stream is overlayed on real sensory stream, it's more like they are different kinds of perception, like seeing and hearing is, though visual imagery is closer to seeing because objects it deals with have similar perceptive qualities, like having spatial component and colors.

In my case imagined sounds are more detailed. When I'm remembering or simulating a conversation, voices are rather close to that of real people. Music can be recalled quite well too, maybe up to 20% detail level of original. On several occasions a had some excerpts playing unvoluntary playing in my head with like 90% detail level of original. Quite often I got some music stuck in my head. When I'm underslept it's usually some bad quality pop music from 80s-90s that I haven't heard since my childhood.

Tactile, smell and taste sensations can be and are emulated too.

I wonder, do people with aphantasia have dreams? Dreams are fully emulated sensory input, though I feel like they come from a bit different place then imagined input does.

Edit: actually mind's eye is not restricted with field of vision of real sight, it can encompass say 1km sphere around me with very very low level of detail. I think that kind of capacity is used automatically in daily life when you walk somewhere and you have automatically constructed knowledge of what's behind your back.
