Should I submit this as a bug ticket on github? Yes we can definitely debug this
But I tend to think the stock V4L2_CCD driver is vastly incomplete. That's also a bug since all other v4l2 based capture works for both multiplanar and single planar devices.
Here's a summary on the rkisp capabilities.
