Honestly I can see the subpixels of any oled display. This does not happen with high ppi lcds. I don’t know why but the oled subpixels do not blend as well as the lcd ones
Most OLEDs use the PenTile layout, which means that each logical "pixel" only consists of 1¼ subpixels, whereas in RGB panels every logical pixel is always three subpixels.
