I think you’ve hit on what a lot of people have shared over the years. CK’s light skin, etc. has opened her up to pairings (and rivalries) that Mishael Morgan, Loren Lott, or Angell Conwell never would have had. Being in Cane Jail sorta obscured those advantages (even though, of course, he was white). But Y&R clearly sees her as palatable enough to the aging white audience to be a lead. She’s seen as formidable enough to go up against another longtime (white) lead, AH’s Victoria.
She barely interacts with her black family at all, and her mentor is her dead white best friend’s mom.
