New Valyria culture

[Sauliukzz]

I have a question. Why when you playing as New Valyria or Volantis, the culture and religious conversion of provinces (mostly ruins) are not the same as you characters? Is it because of the dying breed of Valyrian religion/culture? Any way to change that, without modding the game?

That's because Volantis province has the Volantis culture while the Triarchs are Essosi Valyrians. Completed ruins take the religion and culture of your capital county. You'll have to convert Volantis before colonizing if you want the Essosi Valyrian culture to expand.
