[SOLVED] Is this early signs of disc rot on DVD-ROM/BD-ROM?

Looking to my collection i have been noticed that there are some marks on the edge of the game discs, like glue or adhesive of the discs squeezed out from the outer edge, for example this Xbox 360 DVD-ROM:

In the reflective part looks like this, with the gold reflective but the other sectors are silver, that gold reflective is brozing?

This is an example from a user of reddit with a similar case of my BD-ROM Xbox One games but is less visible; they looks like little bubbles of adhesive:

I should point out that it is not as if it were the exception, if not rather the norm, the majority that I have looked at have said marks to a lesser or greater extent.

Is this early signs of discs rot? I have not found nothing similar to this.

Those look like molding defects. Or scratch/bump marks which appear during regular use. Rot begin as darker dots on reflective layer that slowly turn into areas of different color.

Are game consoles, so... the consoles could heat the discs and produce that the lacquer squeezes out a bit?

My main concern if that is going to be disc rot more soon that long due to this, and i have the thought back in my mind if could be sun damage of my room, it's indirect sunlight, but when i open the windows and it's sunny outside cristal and the wall of the balcony reflects the sunlight from outside, could that produce the gold reflect of the discs of the second picture or the lacquer on the edge?

It's more ambient sunny light that anything else, but maybe when it outside at 35°C could heat my stuff improperly

In dry and not extremely hot place those discs should live long enough. Indirect sunlight usually is not a problem.
