I did not, but i did expect more from that Story arc this time around.
Who knows, there may be more - just hidden. On top of the things DefaultDanlelS mentioned, there is also hard to get shard outta one of the two SSI black team agents, ones who try to escape in a cloaked AV (which i think is a nod to thermooptics in Ghost in the Shell (1995) classic of cyberpunk genre, seeing how "tank" in there uses it). And if it is, perhaps it's somehow possible to actually ground / take out that AV - would be logical, given how Kusanagi's partner ends up taking out that tank in the anime, using some "standard issue big gun". I plan to try that with HMG and some other big ones during my 2nd playthrough (long time ahead) after getting level 50, so for now have no idea if it's possible. The thing just flies away and disappears, otherwise, so nothing there.
There is also the whole rings deal / hidden lore. Note how mr. Peralez wears a certain ring with couple letters on its top. Well, Hellman wears the same ring. V's boss in "Corpo" start also wears it. Garry the prophet wears same ring, also. As do few other mysterious, "custom-made" NPCs in the game. And Blue Eyes Man also wears one, 'cept for him the ring's golden, not silver-like. Clearly, it all can't be just a coincedence; there is some kind of secret society and/or education and/or indoctrination which all those characters have in common, thus the ring. Personally, i suspect those are the people significantly involved in the endeavors and actions of the emerging AI collective, in a way which makes them at least partially aware about what the nature of that AI collective they are working with/for.
And it wouldn't surprise me a bit if much of Peralez story would be hidden / secret - we have secret ending, we have at least one whole secret quest - one which never starts unless certain things are discovered by manual exploration, and which does not give markers for "next objectives" like usual quests do. So if those exist, then why much of Peralez story could not be hidden, too.
P.S. Recently, i made a topic about whole Peralez situation and "Dream On" side job - here:
