This is obviously a photoshop/troll post.
Zoom in using any image editor and you will quickly see that the dot was photopshoped on there using a 5 pixel wide brush stroke.
You can notice that all the real holes are elliptical shaped and match the lighting/depth, while the dot in question is a 2d patch added on there.
I'm with you on this. There's actually a thread on 4chan's /g/ board about this thread right now.
