DRM (Netflix) not working on OpenCore AMD Ryzen 1600X and Radeon RX580 based iMacPro1,1 Hackintosh running Catalina 10.15.4

Hello there,

I am running an OpenCore Hackintosh Catalina 10.15.4 install on my Ryzen 1600X and Sapphire Nitro+ RX580 build. Everything is working and absolutely stable. Except DRM. I cannot get Netflix in Safari to work. It just shows a red screen which then goes to black. Subtitles are showing but not the movies themselves. I was running the MacPro7,1 SMBIOS before and was hoping changing it to the iMacPro1,1 would solve the problem as pointed out by u/jspiropoulos somewhere in this sub, but it is still not working even tho I am running 10.15.4, have a genuine RX580 and the iMacPro1,1 SMBIOS with a valid serial. With the MacPro7,1 SMBIOS I also tried the shikigva=128 boot-arg, but that didn't do anything either.

Does anyone here have an OpenCore AMD build with an RX580 and got DRM working? Any help or advise would be greatly appreciated. I've been trying to solve this for a good two months now.
