Absolutely. She is the holy quadrilogy of the narrative the media pushes as "least likely to be a serial killer": white, attractive, middle class, straight.
Change one of those things and the media handling would have been quite different. There is no way she'd have been given this much leeway if she'd been working class, non-white, lesbian/bi, or fat and ugly. The media never gave this much leeway to the murderers of Star Hobson and Arthur Labinjo-Hughes., for example. Letby didn't kill just one child (as each of the convicted women in those cases had)
