According to this Supernatural Wiki, the white-eyed demons are Ancient Demons (See also Demon Page Types of Demons)

According to the Super Wiki (The Supernatural Wiki on MediaWiki), in the Knights of Hell and Princes of Hell pages stands the white-eyed demons are First Demons

If they ask me, the white-eyed demons might be something like the Emperor of Hell and / or the Highest of Hell
