Websocket Compression In Mobile Safari

Hello! I was wondering if it’s possible to tell whether my cordova app is using permessage-deflate. I know it’s supposed to be enabled by default in Meteor 1.2+ but it feels like my app is taking suspiciously long time to download the data so I’d like to know whether the ws traffic is compressed. The server is hosted on Heroku.

Safari Inspector is not much of a help, sadly, as it doesn’t show websockets.
