If you mean does the higher edition game come with an extra set of clothes for NPC characters for a region then yes it does.
Per PDX Nicou:
"Flavor Packs aren't 100% cosmetic. They are in-game content focused on a theme or a region, to add some spice to themes and specific regions of the world and give everyone something to spend your time with. "
Just wondering. Are flavor DLCs more like portrait and unitpacks or do they also contain gameplay changes like the region DLCs of EU4?

Going from EU4 flavour packs it more like pin-point upgrades to small areas to bring some more game development to a region. Example I think would be:
Europa Universalis IV: The Purple Phoenix Expansion
Europa Universalis IV: Purple Phoenix DLC adds new, unique events, themed event pictures as well as several new unit models to the Byzantine Empire.
Europa Universalis IV: American Dream
Europa Universalis IV: American Dream DLC adds over 50 new, unique events, 10 themed event pictures, as well as several new unit models to the United States of America.
Europa Universalis IV: The Stars and Crescent Pack
The Star and Crescent event pack enhances the gameplay for rulers of the Muslim faith in Europa Universalis IV.
A total of 70 new event pictures contained in this package adds visual flavor to the gameplay experience. This event pack also contains several new events and event chains for Muslim rulers, adding to the gameplay immersion.
Those were released at the same target price they are quoting for future CK2 mini packs.
