It does, but I think is very improbable.
There is no water or some kind of food in there.
I've just sent an email to Davis as well to ask them if they had seen anything like
this on other customer consoles.
I think you underestimate what some microorganisms can survive or even multiply in. As two examples, look up Deinococcus radiodurans and chemolithotrophs. Again, organisms living in jet fuel do no have much water available.
As for your second approach, I agree. You don't have many options:
1) Live with it
2) Try to get a replacement screen
3) Trash it
4) If #2 or 3, then investigate what it is. A decent microscope might reveal whether the defective areas are shaped like pixels or more amorphous. Pixel ("point" ) defects are well known. If amorphous, any microbiology lab could help identify whether bacteria, fungi, or something else. Something else might include a change in form from liquid crystals to solid crystals.
