There is a fair amount of cross-compatibility between processors from the same architecture so it's reasonable to spoof the IDs (but you may also try 0x0412).You say I should use although it's Iris pro 5200. Fine
I'm currently setup as iMac15,2. Should I switch to 14,1? 14,4?

I would suggest changing one "main" variable at a time. Platform and Device IDs are one "main" variable. SMBIOS is a second main variable, but it is only important in that it should be a non-headless SMBIOS. If an iMac has a Discrete GPU, it will use that to drive the display, which means its iGPU will be running in "headless" mode.
The reason for checking IORegistryExplorer is to determine not only which driver/framebuffer is attached, but also to determine whether display connectors are attached (i.e. non-headless).
