HDCP (amazon prime HD playback problem)

I’m having problem with playing HD video from Amazon prime.

This website says Picopix Max is HDCP 1.4.

This Amazon page says 4K (UHD) requires HDCP 2.2, but doesn’t mention about HD and HDCP version.

Question is, this HDCP version can be updated in the future with firmware update? or rather hardware issue that can’t be solve by firmware.

Thanks,
