The page load doesn't seem to change with "Low Data Mode" enabled on Safari (seeing ~30MB). Does anyone know if there is a way to detect that setting from within Safari? Would be cool to provide a low-fi version of a page if that was detected.

  Interesting. That is a separate experimental low-data setting that's been around for a while in Chrome, but isn't supported by Safari [0]. Haven't run across it before, thanks! For low data mode specifically, looks like you can easily get "allowsConstrainedNetworkAccess" from an iOS app [1], but don't see anything comparable available for Safari or Firefox.
