Currently, the global block message is visibly different from the local one:
Just noting that Special:GlobalBlockList has a similar issue.
Change 842473 had a related patch set uploaded (by Stang; author: Stang):
[mediawiki/extensions/GlobalBlocking@master] Add mw-logevent-loglines class to ul element
https://gerrit.wikimedia.org/r/842473
Found no difference between adding such class and not in Special:GlobalBlockList . A little bit off topic, since Special:BlockList use table to illustrate, maybe globalblocklist could show those logs in table as well.
