I dont think there ever been a official PCI-E 2.0 or 3.0 logo. Just the PCI Express logo.
Both Nvidia and AMD AIBs just slap the PCI-Express (Basic) logo somewhere on the box (Side or Back). Just look at Wizzard reviews for packaging screenshots.
Motherboards are different. Each motherboard maker has their own take on the PCI-E logo. Usually its the official PCI Express (Grey Frame) logo with a gen # added to it on the side or bottom.
