I would look into the documentation and code. We are not studying something
that is outside of our worl like natural science where we observe :)
This here is pure mathematics

correct - this is the window manager ( in my case twin)

I am not sure what you mean

"If your image is 72ppi (pixels per inch), then one point will equal exactly
one pixel. Point is a physical unit of length, used in typography. It's
equal to 1/12 Pica, and 1 Pica = 1/6 inch. So 1 pt = 1/72 inch."

"In applications, a point is exactly 1/72 inches."

this is true

Have you tested anything else?

If you change dpi and restart the window manager I would expect that icons
look different. Perhaps you can test that

Under look and feel -> fonts you can enforce the DPI
