Android apps are written in Kotlin or Java and this means every file will be per convention under com.company.appname(or similar)
And every file will have a line
package com.company.appname
And references to other files in the import.
This means every source code file is changed and therfore recompiled and the update will include the whole app.
Now 35GB means there is a lot of image and/or Audio resources also included. Why this is updated as well I don't know, but their path also changed. Maybe that's enough for the Version control to see it as new.

And that's why you use a separate codename for actual software development. Changing the visible app name should only affect a few resource files.
In those cases, I would leave the internal naming alone. It's not uncommon for software to have a different name internally than externally.
