This bug is definitely real. I tested it with 2 versions of each game. Assasins creed origins and far cry 5 gold edition disks do not display trophy information after they pop, but the regular versions do display popped trophies. I will try it with watch dogs 2 gold edition later.
Another thing I found is friends who own the game are separated depending on what version they own, so for instance if you only have the gold version, only friends with the gold version will be listed under the friends who own the game, and vice versa; which is not what should happen. I'll be surprised if ubisoft ever fix it though.
