I Started with the factory installed .65 then upgraded to .75, .90 and now .99. But everytime that I do that Im not sure if Im actually overlaying the OS or if the new OS deletes the the previous and then installs? Can someone give me insight? Thank you

The installation progress erases the previous OS image on your phone. It's not just adding or changing bits and pieces.
The manual load through DM erases and then loads the new one.
The OTA installs I believe do a binary patch to the files, which basically means the new files will be the same as full install on a binary level. I.e. no difference in the end.
