My opinion is that Iota is the Golden one; it was not present in the symbol but appeared in Season 6 as the gold AI with Maine. (notably the symbol is also differing between season 6 and 10 flashbacks). However, it is also possible the Eta and Iota have converged to make the gold-ish fragment seen in 6.

My theory is that Sigma was incorrect about the original symbol (evident by the 'Metastability not exact') that included Iota. By the time the Meta reaches South and North and takes Theta he will have learned that Iota is not essential.
