We know about the vulnerability, not the payload delivered through it. There could be thousands of them with wildly varying characteristics. There could be none.
Some of them could be rootkits, and have patched filesystem and process explorers to hide themselves. Some could be called virus.exe.
But no, you will never know that you haven't been compromised. In the coming weeks, we may learn about some of the specific malware that spreads this way, and you may be able to test your phone for it, but finding nothing does not mean you haven't been owned by something more exotic.
I don't see where superuser2 said what you attributed to them.
Did they edit their comment between the time you quoted it and the time I posted this comment? Or did HN's quirky rules regarding newlines (gotta put two if you want to display one) change the meaning of your comment?
