It is more convenient to use a higher level tool:
For a quick look it is more convenient to use `systemd-analyze dlopen-metadata`:
```console
$ systemd-analyze dlopen-metadata /usr/lib64/libsystemd.so.0
FEATURE DESCRIPTION SONAME PRIORITY
lzma Support lzma compression in journal and coredump files liblzma.so.5 suggested
lz4 Support lz4 compression in journal and coredump files liblz4.so.1 suggested
zstd Support zstd compression in journal and coredump files libzstd.so.1 recommended
```

Another higher level tool is `dlopen-notes`:
```console
$ dlopen-notes /usr/lib64/systemd/libsystemd-shared-257.so
# /usr/lib64/systemd/libsystemd-shared-257.so
