I don't use Galaxy, but if you're talking about your GOG profile page on this site, the DEMO and full version should be different. I have the DEMO, which the image still shows Ion Maiden, Ion Fury(the full game), and Bombshell right next to each other. My games are sorted by order of purchase, so it may be in a different place for you.
In any case I also did not get any update notice and only came here after starting Steam and seeing the full release on the main store page. In my Ion Maiden download it does say 1.0, but I'm installing now and have to see what it says in-game....
