Questions regarding AFBC format support on Mali GPUs

I am developing a game with Unreal Engine 5.5.4 and am considering implementing AFBC along with UBWC. I have been using the R11G11B10 format but am considering changing to R10G10B10A2 and R8G8B8A8 to support older devices.

  1. What is the minimum Mali GPU version that supports AFBC for each of the following formats: R11G11B10, R10G10B10A2, and R8G8B8A8?

  2. If the support for these formats differs between OpenGL and Vulkan, please provide the specific details for each API.

  3. I have seen advice to determine if AFBC is working by monitoring bandwidth. Is this still the only method to verify it?

Thank you.
