If you’re saying that the 90s shows have more direct references in Lower Decks than Discovery, I can agree.
I’d add The Animated Series too though. There are many Easter eggs from TAS included.
However, the OP should be aware that Lower Decks is written to be enjoyed by those completely new to the franchise. The deep cuts are added value not a necessity. There are numerous new fans that watched Lower Decks and only later got to the other shows they reference and enjoy discovering in reverse.
Discovery in-universe becomes a secret at a level that it’s not the kind of thing the Cerritos crew would know about from reading historic resources.
