1st, as I said, this is an unproven hypothesis. 2nd, the dominant impact on reported prevalence rates are 1) social acceptance of those identities, and 2) the relative risk in revealing those identities. If being stoned to death is the risk faced for being gay, people won't tend to admit to being gay to a researcher.
> social acceptance of those identities Why would it not work the other way too? Maybe the Western society is hell bent on putting people into boxes, whereas people in third world countries are willing to look the other way for minor deviations [sic] as long as they're useful to their family / village / society?

That being said, gender dysphoria especially does have biochemical component. Most men would feel horrible being on estrogen, most women would feel weird being on testosterone. That's true for both trans and cis people, not 100% of the time, but often. That's how they got Turing killed.

Dysmorphia is a disordered body image and obsession with flaws in yourself. Dysphoria is a persistent feeling of distress related to your physical gender characteristics and/or gendered social expectations.
Of course, where the lines blur is when people speak in memetic terms of male-to-Male transition: stuff like looksmaxxing, where dysmorphic body image stuff is mixed with toxic culture relating to the pursuit of high masculinity and acting tough in a certain way, to be more of a man, or something.
