I switched on the D3 and used the code example above on a D-Duino-32 (with, obviously, an X2812B on top) but the four pixels still remain white.

Where I'm wrong?

Use the GPIO number (I think it's 0 zero) - I had a similar issue. There is some timing issue with the display and the neo-pixels when using the D-Duino32. That issue doesn't seem to be there with the D-Duino ESP8266. Here is my instructable if you are interested.
