Okay, cleaning this up a bit. The following files can be found in the vendor tar ball, but end up modified in the blob build image. I’m not worried about the .apk/apps (signature, libart), but it looks like the .so’s below get modified during the build.
- 49a74eba45617e5c98d876d26d6ca1e6 lib/libaudioroute.so

Let’s have a closer look: Just GPS and audio/radio and, oh joy … “fitness-tracker” stuff (“ant”)?

Most modified (different file size) between the versions are:
lib/libart-compiler.so (snap in replacement)
lib/libwifi-service.so (snap in replacement)
vendor/lib (all added from the tar ball, except the stuff mentioned above.)
bin/wcnss_service (snap in replacement)
And of course a lot of new stuff gets added to /etc (certs, firmware, permissions, debug-levels, calibration, wifi). Around 60 apps go into /app/ and bin/ gets around 100 new files as well. (All tar ball based not newly created).
