Android Antialiasing - how to?

I’m having problems with enabling Amtialiasing on mobile devices in Unreal Engine 4.27. I’ve followed this topic:

but it doesn’t seem to help any way. I’m running the app on Shield Tablet and on Xperia XZ1 devices.
Here’s my android CVars in Device profiles:

And here’s the result with printed CVars after running the app on XZ1:
(no Mobile HDR - is this the problem?)

For some reason sg.AntiAliasingQuality is set to 0, despite the fact that in Android Devices it’s at 4. any help?

Funny thing is, if I use ExecuteConsoleCommand on begin play for post process quality 3 and antialiasing quality on 3 it doesn’t change a thing.
