I have a pair of generic OLED displays here. Both were bought from Tinkersphere here in NYC and seem to have an almost normal interface. That is both resemble this fellow https://parallax.com/product/28087
I say "resemble" because obviously their OLED boards aren't same as the one shown there. However I believe the driver chip is the same one as described with one from our hosts.
Interestingly enough the firm is aware of Parallax, but they seem to be primarily an Arduino and Raspberry Pi shop.
For example tinkersphere.com/oled-displays/805-white-oled-module.html
and that is one of them.
