Problem with camera profile

Hi there!
Im using NLP2.2.0 and NIKON Z7ii with 55 f2.8 macro lens atm.
Cant find nikon z7ii profile in camera profiles folder,
scaned ektar100 (1st pic)and portra400 (2nd pic)convert with same configuration just changed WB (ektar100–>Auto Warm, portra400–>Auto Neutral ),if i leave with same WB the tone of them will looks exactly the same .
In this case, is there any possible because of lacking with nikon z7ii profile?
and how to create a new camera profile?

thanks a lot!

this one is from portra400
