@DexterOX Do you happen to know if the real 2019 imacs display the graphics in About This Mac as "Radeon RX580" or "AMD Radeon RX580"?
The real iMacs 19,1 don't use RX580.
But if you want to see how a real iMac 19.1 shows, look at the image

@DexterOX could you please check in the real iMac ioreg. is Intel using Accelerator from KBL or CFL? My intel shows framebuffer CFL but Accelerator shows KBL.

I also checked IGPU picture previous page you shared. Your ig-platform-id and device-id are same. My ig-platform-id 0300913e and device-id 983e0000. are you inject intel?

HI!
Look at the following images are from the real iMac 19.1

IGPU

is necessary to add IGPU "AAPL, ig-platform-id" = 0300983e in clover to be recognized as "Intel HD Graphics CFL" like real iMac 19,1 you need change 0300913e => 0300983e

I am using iMac19,2 on 10.14.5. I could notice any difference when setting SMBIOS to iMac19,1 or iMac19,2.

Motherboard: ASRock Z390M ITX/AC with i8400 and RX580.

Would you please share your config.plist file? Altough I changed it to 0300983e I'm having Intel UHD Graphics 630 instead of Intel HD Graphics CFL :/
 
You need delete WhateverGreen.kext
Are you sure? cause when I deleted it I can't make a boot. After loading screen, it gives me panic. I checked in -verbose and it stuck on IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0. Then turns kernel panic.

Could you please share your config.plist without SMBIOS.
