Similar IQ Pentax Equivalent?

I've been enamored with Ricoh's color science since the release of the GR3 and love the camera very much but have been slowly getting tired of the subpar autofocus and the lack of a proper viewfinder. A lot of the times I don't mind having a slight larger camera either.

Do any of the modern (2019+) Pentax cameras have similar color science? I'm particularly looking for the Positive/Negative film and High Contrast BW in an ILC package but have never heard of anyone speaking of the 2 brands color science similarities. Does anyone here have experience with recent Pentax?

Thank you.
