Divine eye is abhiñña. But seeing kalapa is merely vipassana knowledge.
You should ask your ebt teacher (Ven Ariyadhammika) about the difference and as it relates to kalāpas… He will be able to tell you the Classical way they are different.
I suggest you learn abhidhamma first and watch some videos by Ven Maggavihari on rupa. I also suggest you refrain from writing books until you get more educated in Classical Theravāda. Why not wait 5 years?
