In CK3 cultural names for titles were decided based on the culture of the independent realm that conrolled them. All of the counties under the Byzantines would have Greek names, the counties under the HRE German names, etc. Now to get all of the titles in your realm to use names based on your culture you would need to revoke all of the ones held by rulers of different cultures and replace them with rulers of your own. That just isn't possible or very fun most of the time. There are pros and cons for the ways CK2 did cultural names for titles and CK3 does currently, so I think it would be nice if players could have access to both. One where cultural names are based on the culture of top liege of the title and the other where they are based on the culture of the holder.
