Re: A new OS from Google
The differences can be substantial, and unless you're decompiling the binaries, you have no real indication of what the differences actually represent. They could be the inclusion of telemetry code, they could be the result of using a different library or version of a library, or they could even be the result of different optimization methods.
A telemetry package would not be likely to stand out, particularly since telemetry code tends to be reasonably small and simple.
