Does this look like corrosion on my toilet water supply line?

Had the plumbing redone with pex approximately 5 years ago. I noticed that one of the fittings under the toilet appears like it may have some corrosion. i checked the other fittings around the house and they have some faint green dots visible under the tape. Is this something I should be majorly worried about?

Look more like a coating of dog hair, dust, and dirt!

I don't see any issue. Some chromed fittings will see the chrome corroding or peeling over time, but it doesn't affect the integrity of the valve. Unless you start seeing any dripping water, you're all good!

That light green looks like thread sealant compound applied over the teflon tape.
