0,-90,0 will give you the same result as a polar coordinate transformation in Photoshop, so worth a try. Effect is more pronounced when some object are above the height of the drone (closer to the ground).
I posted this example earlier regarding noise:
https://phantompilots.com/attachments/noise_sample-png.93148/
quoting myself: "here is a 100% crop (ie fullsize pixels) sample of a high-contrast and shadow-lifted iso 100 capture from yesterday.
Along one axis, color noise is reduced (lightroom setting 50), and the other luminance noise is reduced (lightroom setting 15).
As this demonstrates, color noise is the deamon here, and must be addressed for a good result."
Note that I have had two
p4p, and they had the almost exactly the same noise-profile so I assume it is a general problem.
