iOS upscales 120 → 180 px, so the icon looks blurry on Retina screens.

There is no maskable icon, so Android shrinks the regular one onto a white circle.

Questions about the github.com favicon

Where is the github.com favicon?

The main one is at https://github.githubassets.com/favicons/favicon.svg. The default path, https://github.com/favicon.ico, also returns an icon.

What size is the github.com favicon?

favicon.svg is a vector file, so it scales to any size. The largest raster icon on the site is app-icon-512-7f9c4ff2e960.png at 512×512 px.

Can Google Search show the github.com favicon?

The site meets Google's rules: favicon.png is a 32×32 PNG file (958 B) and robots.txt allows it. Google recommends more than 48×48 px, so a larger icon would look sharper. Google still decides what it shows.

Does github.com have an Apple touch icon and a maskable icon?

The Apple touch icon is 120×120. The manifest has no maskable icon, so Android shrinks the regular one onto a white circle.
