imac19,1 + i9 9900k: wrong CPU in About this Mac?

I just upgraded to the latest Clover and 10.14.5. I changed my product model from imac18,3 to imac19,1 in SMBIOS.

I was under the impression that About My Mac would probably show that I have an i9 9900k but instead it shows "3.6GHz Intel Core i7".

Is this normal? Is there anything specific I need to do to make it detect my CPU correctly?

Thanks!
