Is “The Investiture of the Gods and Journey to the West have different settings for the Dragon King of the West Sea.” true?

In "Investiture of the Gods," the West Sea Dragon King appears as one of the Four Sea Dragon Kings. In Chapter 015 of "Journey to the West," the West Sea Dragon King Ao Run is the father of the White Dragon Horse, who reports his son to the Heavenly Court for burning the pearls.
