White-ish lens issue in corners?

I have the Sigma 24-70 DG DN and I'm seeing an issue in my corners at some focal lengths. There is a weird white-ish lens distortion, almost like an opposite vignette that tapers into a regular vignette?  Pretty sure I got a bad lens... but it's past the return date. See upper corners on this image.  Is it something dumb or does it need repair?
