Show us a picture of your OLED. Also, try to look for pictures of similar boards on online malls and see if any of them mention the driver chip used. Some might mention a driver chip other than SSD1306. Many bulk sellers don't really keep track of such info, especially if they are offering a selection of boards.
White dots on black sounds line random data. Yeah, I've seen that once -- I bought two types of OLEDs from a seller selling cheapo stuff. One worked with the SSD1306 Pico C SDK example and the other turned out to be SH1106. I had to change a few lines to get something on the screen, because while the startup sequence is compatible, SSD1306 has more convenient auto-increment across memory pages so it's easier to push data.
