All the Devs said is that the Allag called powerful Primals Eikons. That doesn't mean that all Eikons are Primals. Unukalhai says it's a word the Allag used to refer to godlike beings. I think it's as simple as that. All godlike beings can be referred to as Eikons. Primals are specifically entities brought into being and sustained with prayer and aether. Unukalhai heavily implies that Odin and the Warring Triad are not Primals.

Ferraris and Jeeps are both cars, but Jeep isn't just another word for Ferrari.
