No, this is not a sign for anything.

I wouldn't be so sure. You are exchanging the binary and stuff it links
to (see below answer to the size)

Upstream doesn't do that.

And LO uses internal libraries - and that includes libepoxy.
So there's a internal libepoxy involved in the upstream build (which is most
probably even statically built/linked, so that would explain why upstreams
version is bigger).

Upstream has the same version, though.
