I don't know where else to post this but I believe this forum may shed some light on this issue. I was checking my game collection and I found out that most of my discs have these tiny pin-holes which aren't visible unless I look at the disc behind a light. On wikipedia, it says that these holes are disc rot?

It's the little white/colored dots https://imgur.com/a/ZxrSz8K

All of these discs are still readable, including spyro trilogy which seems to be the worst out of these. I keep all my games in the closet, in a non-humid room with normal room temperature.
I took these pictures of my blu-ray discs only but there are more of them on some of my oldest PC games that are on discs too such as Dark Colony and Jane's IAF.

What I also noticed is that games with plain metallic disc cover print have more of these dots than those with a printed image on the disc. Can anyone shine some light into this? No pun intended. Also I can provide more images of the CDs and DVDs.
