Not much more complicated than IPv4. There are more bits. The addresses are longer. It's not hard to grasp if you understand the prerequisites to understanding networking in general.
The idea that it’s just “more bits” it’s wrong, so I’m not sure your assessment is valid. Maybe at the packet level it’s just “more bits”, but at the network level a lot of processes changed. IP assignment, router discovery, etc. are different.
