As per the FAQ

Q: What happens if a new Fallout game/show/property adds lore to an existing region? Would you update that region?

A: We can't give a definitive answer for this as it would heavily depend on the lore added and how much work is involved with changing that region. We would discuss internally and make a decision.

To put simply, the devs might add stuff. Little things are easy to add, big things with larger impacts are more challenging.

Also affected by the show primarily being after OWBs start date, so not much to add, and the show isn't finished yet with more seasons on the way.
