Is the EU scenery dlc on steam the same quality as the online streaming scenery?

Wanting to save some space on the ssd and wondering if the steam dlc of EU and USA are the same quality as the streaming data?

Quote from Jet-Pack (IPACS)

To my knowledge they are mostly identical but with the DLC installed you can obviously fly across Europe even when offline.

Thanks, pretty much always online so will remove the DLC to save some space.
