That pink hue usually ends up being related to white balance or ISP tuning rather than the sensor itself. I’ve also seen it happen under certain lighting conditions where the auto settings overcompensate a bit.
Might be worth checking the raw output vs processed output to narrow it down. If the RAW image looks fine, then it’s probably somewhere in the color pipeline.
Also, for comparing the tint between frames, I’ve used https://colorpickerimage.org/ before to inspect the actual RGB values in different areas of the image. Makes it easier to confirm whether the pink cast is consistent or only affecting highlights/shadows.
