While your EFI config has improved the 4K situation, one area where I'm having trouble with it (vs my EFI which was masquerading as an iMac19,1) is with the services. I updated the config plist with values for SN/MLB/SystemUUID, but none of them work and every time I try to login to iCloud I get...
