Like +80% of the populations is Mestizo, but sometimes you see a “white” Mexican who you’d think is greater than 3/4th white, but they take a DNA test and they’re actually half native.
Basically, even if you’re a halfie, sometimes genetic recidivism dictates that you’ll get “all the white genes” and hence look indistinguishable from most purebloods. In heavily mixed nations such as Brazil this is a well-known concept, when your brown but one of your kids comes out black, one white, and the rest intermediate, but it’s a bugger issue in unmixed nations or nations that don’t think of themselves as mixed. Look up “torna atras” for more information. Basically, some Iranians have more brown admixture than others, someone from thr Northeast, say for example, a Talysh is not going to look anywhere like most Baluchis. A lot of Iran’s politicians are Azeri (Azerbaijani) but Azeris don’t have much Turkic admixture, they’re mainly descended from local West Asian and Caucasus populations that simply spoke Turkic due to the prestige of the ruling class and assimilation, so they look white. Some Iranians, even if they have less white admixture, can still come out looking more white than someone who’s predominantly aryan
