Do World customizations affect the seed?

In Minecraft, you can build a world using a World Seed. Using this seed, you ca recreate this world over and over again.

However, there are things that affect this. For example, using a seed from an earlier version of Minecraft (e.g., prior to biome additions like mesa and savannah), the seed will generate a different world.

Is this the same for a "customised" world? I recently created a world in where I ramped up the dungeon spawn rate to max. If I recreated the world using the world seed, but with less dungeons, will the world be the same?

What can affect the world generation using a world seed in the customisation options?

Solution 1:

As mentioned in the comments, dungeons and other structures are generated after the rest of the world, so you would indeed see the same world, just with an increase of dungeons inside it.
