Primal confusion - spoilers

[Enkidoh]

As we are told, Eikons are not simply Primals by another name as the Garleans like to think. They stole the word from Allagans, and the Allagans used the term for something much more powerful. The Eikons we know of right now are Odin and the Warring Triad.

But isn't this just the same thing - an aetheric entity that is summoned? Even back in 1.0 it was made specifically clear the term 'eikon' is just another name for Primal (it is a Greek word where the English word 'icon' is derived from), hence the Garleans used it as a derogatory phrase (so much so, the beastmen actually hate the term) - early in the 1.0 Gridanian story Miounne actually used the term in that way, and Nananoby during the Path of the Twelve story actually chastised the player's Path Companion for using it in such a way:

Path Companion: "Do the eikons really have the power to move the hearts of so many?"
Nananoby: "You had best not speak that name around the beast tribes, lest you incur their wrath. 'Eikon' is a derogatory term used by the Garleans to reflect their belief that the Primals are not true gods, but mere beasts which the ignorant tribes mistakenly worship."

Of course much has been retconned from 1.0, but given the fact that throughout ARR's main scenario the game's narrative pretty much upheld this idea of primal=eikon, call me stubborn or in denial, but I'm still sticking to this definition.
