[Question] μcode for Crystalwell CPU missing in UBU?

BIOS/UEFI Modding BIOS modules (PCI ROM, EFI and others)

I’ve noticed that some Intel 8/9 series motherboards’ BIOS contain microcodes for Haswell (CPUID: 306C3) and Crystalwell (CPUID: 40661). After microcode update with UBU, the Crystalwell one disappears.
An example of Crystalwell CPU: i7-4770R
