All that being said, in my experience all the photos I've taken exaggerate the lighting gradient. I find them helpful for identifying that the issue exists, and making comparisons between units in the same photo, but none of the photos I've taken accurately represent what I see in real world use.
I imagine that if I put my iPad Air or iPhone through the same process whatever inconsistencies in the screen would start to show up. And that's why I'm not ;-)

I've just put GIMP's eyedropper to the picture, trying to pick the exact same pixels within the middle of the original and pasted lightbulbs.
If the bottom one is an exact 1 to 1 copy of the top one, without any other edits to the picture, the eyedropper should return the exact same value for both (or at least, nearly identical), regardless of what I'm seeing.
It doesn't. The lower pasted part is decidedly more yellow than the top one, not only to my eye, but only to the eyedropper.
What could be causing this?
