I am not sure if it is at all possible under Apple HIG but just want to check if we could at all achieve this.

I have see this is done in the System App "Newsstand" . If you see the color is now exactly black or white. It is actually a light gray .

I Don't think you can change the text color of Status bar. @JMarsh its not duplicate que. The link you provided is for status bar style not for text.
