No one uses hardware decoding for images - it’s just not a good fit for the reality of how we use images. Images are small and easy to decode, whereas starting up a hardware decoder takes a non-trivial amount of time. Additionally, GPU decoders only work single-threaded, so each image would have to be decoded one by one, instead of all at once like with CPU decoding. This was already attempted with VP8/WebP and they gave up trying to make it any good. Videos are good candidates for hardware decoding since they’re large an you’re only looking at one at a time.
If you have benchmarks or some proof showing otherwise by all means post here.
Graph conveniently omits hardware support, where avif (av1) is supported across the board

Funny enough, JXL is supported anywhere you have a general purpose CPU, which is anything consumer with a GUI!
