I have now ordered the OLEDs from three different vendors. Two of three times they had the "right" pinout (the pinout I used for the PCB design). The other time the VCC and GND pins were swapped. On the first picture you can see how I fixed this problem.

The last displays I have ordered, came in these nice cases. I have to build a project which fits in there. (thinking of an ATtiny and a coin cell, ...)

It might be of interest to you to place another header on the board, where you can solder in the display upside down and fix it in software?

Great idea, with this method I could also use the same mounting holes. The OLED library I use has a function to flip the display, so this would be very easy.
