This is probably obvious, but I feel a need to say out loud: The only reason why #Voyager and other #StarTrek stuff featuring holodecks doesn't mention holodeck programs based on movies recent when the series were made is copyrights.
@Anke Watsonian answer is WWIII and the Eugenics War (or have those been retconned away?) iirc one was 80s and the other in the 90s. But yeah, studiowise it's legal issues. (It's not like they're that committed to continuity)
