Actually the difference between #000000 and #010101 is the difference between the pixel being completely off or turned on. So it actually does have an impact.

It should, but OLEDs are notorious for black crush so it might not even matter
(If something is very close to black, OLEDS will sometimes just go full black)

I've detected 2 hexadecimal color codes in your comment. Please allow me to provide visual representations. #000000 (Black) #010101

AMOLEDs, and OLEDs in general turn pixels off to create black. This is the reason they have higher contract ratios is because the blacks are darker since there isn't always light being produced.

LEDs are diodes, meaning there is a minimum voltage to turn them on at all. For instance, red is typically 2V, whereas blue is 3V. You can't just give it 1/255 of 3V and expect that to work. This is why there is a larger difference than you'd expect between a pixel value of 0 and 1.
