If you are using an iMac19,x SMBIOS then the system would have a Retina 5K screen. But maybe not provide the ability to change the refresh rate for the internal display.
Disabling the IGPU and using iMacPro1,1 or MacPro7,1 with the new dGPU providing all graphics processing, might give you that option in macOS.
