Attached ioreg with Clover patch PEGP to GFX0Ioreg file show GPU is linked to PEGP, H264 GVA decoder work, H264 DRM video should play but HEVC GVA decoder will not work. You can use Clover ACPI patch to rename PEGP to GFX0.

Issue should caused by dylb cache or DRM preference not WEG, see attached png, WEG kext is applied and iTune video work.
If you had replace or restore AppleGVA.framework before, should run below command
sudo codesign --deep -fs - AppleGVA.framework
sudo chown -R root:wheel AppleGVA.framework
sudo update_dyld_shared_cache -force
If stiil not work, try reset DRM see below link
I'll try on a test disk for WEG and DRM reset,
