Perhaps one way of doing this might be

1. Build two test pages - one with compressive images, one without
2. Find the crappiest device with a DPR of 1 and run Android 4.x and Chrome
3. Use Telemetry (http://www.chromium.org/developers/telemetry) to profile
the pages loading on the device

I'm quite happy to have a play with this to see if it gives us anything
meaningful but can anyone suggest a suitable device?
