Webrender is supposed to be enabled by default on this device. (If it's the version with the Mali GPU then on nightly only, if its the version with the Adreno GPU then on all channels.)

So is this not the correct behaviour?

Andrew, do you know what the status string should say in this case?

We've tested with Samsung Galaxy Note 8 (Android 9) - SM-G950F Mali G71, and Samsung Galaxy S9 (Android 9) - SM-G960F Mali G72, both Mali-G devices, both Mali-G devices.
I'm not sure which of the status the feature should have: "available by default" or the "available by user: Qualified enabled pref".

I expect to see "available by default" as reported. We inverted the logic in bug 1668360. It should work the same as before.
