Monitor settings and ambient light will affect how visible the noise is.

Which is the exact reason I want to find a way to actually measure noise—the human eye is so easily tricked. I can't afford a program like Imatest though so I'm praying for a solution that already exists in a program to which I have access.

One of my kids has MatLab on his laptop, does that have a noise-measurement component?
