Ok so let me preface this by saying that I’ve put very little thought into the subject lol. 

So lets say you live somewhere that causes a strong gradient. 

Does it make sense that a narrower field of view would produce images with a less severe gradient than wide field images?

As in… a narrow field image would be easier to correct?

Thoughts?

Yes, that‘s basically correct (for my light pollution): The gradients in my 500mm FL images are far more complex than at 1600mm FL. There‘s also the possibility of using a wider-field FOV to correct the gradients in the narrower field. I‘ve used that technique and it worked well.
