Where can I find comparisons between high resolution and low resolution macOS icons?

In the 2013 OS X Human Interface Guidelines, Apple wrote > As the canvas size decreases, you have fewer pixels to draw, which means that smaller sizes should be less detailed. For example, the smaller size Calendar app icon is not as detailed as the larger size, where you can see numbers for the days of the month, highlights in the metal rings P. 118 I’m looking for a comparison for more their icons; mail, safari, pages. I’ve only been able to find changes over years and not different versions in the same year.
