Mip Streaming on Android, SystemInfo.supportsMipStreaming is 'true' now

Is anyone having success with mip streaming on android? As of 2018.2.0b8 supportsMipStreaming is returning true on android builds on my S8. But on both 2018.2.0b8 and 2018.2.0b9 I'm not seeing any change in memory use while the windows standalone builds work fully as documented here: https://docs.google.com/document/d/1P3OUoQ_y6Iu9vKcI5B3Vs2kWhQYSXe02h6YrkDcEpGM/edit

Texture2D.streamingTextureDiscardUnusedMips is true.
Texture streaming is enabled on all quality levels with a memory tight budget to see how it works.
Tried standard RP and LWRP with GLES2, GLES3, Vulkan.

When I loop through my textures at runtime on android to check them I'm seeing .loadedMipmapLevel is 0 and .streamingMipmaps is true. When I lower streamingMipmapsMemoryBudget on windows builds I am able to see the lower mips but on android nothing happens.
Any suggestions?

Thanks LeonhardP, switching to lz4 compression did the trick!
