Color or white balance shift when zooming on Lr on iPad

I am seeing a very strange behavior on Lr 6.1 running on iPad Pro 10.5 / iOS 14.4. I have a picture in DNG format I have color corrected using a combination of temp increase and some color mixing. When I pinch out to zoom, there's a considerable amount of color shift, as seen in the video I attached. Several of the pictures from the same session/device (a drone) represent the same issue. But I can't readily recreate the issue, and can't find seem to trace the culprit to a specific file type, edit sequence, or source camera. Anyone with similar issue or have any idea? Thanks.
