Matrix of hardware and OS versions regarding UIImage webp support

We would like to switch our backend image pipeline to webp as it offers better quality/compression for our assets.

This works nicely for combinations of modern OS versions and modern hardware, but it didn't work for me with tvOS 15 and Apple TV.

I know that it's possible to check for h265 video decoding support with code like VTIsHardwareDecodeSupported(kCMVideoCodecType_HEVC) - is there something similar for checking of webp support?

Or is there any documentation which gives me a matrix of hardware/software combinations supporting webp? I would be interested in hardware running iOS and tvOS.
