Unwanted texture compression on Shield Tablet

Since swapping to Unity 2019 and Gradle builds, my textures are suffering visible compression on my nVidia Shield tablet where they don't on my Nexus 7 or phone. My large textures are colour compressed, posterised in the darks and with rainbow artefacts on a large transparent 'cloud' texture.

How do I go about getting quality textures on the Shield Tablet?

 

Do you have different build target for Shield Tablet? Or do you build just one .APK for all devices?

 

One .apk (.aap!) for everything.

 

Do you get any adb logcat errors when you start your game in Shield Tablet?

 

No errors. Tried setting texture compression to DXT (Tegra) with no change,. This looks suspicious though, as though 16 RGB buffer is being used...

I changed the Project setting to 32 Display Buffer and that's worked. Would be nice to understand why and what's going on though.
