"Pretty consistent"? Consistently what? They consistently get smaller with distance. This is the opposite of what your theory predicts.
They are fairly consistent. Any one-pixel-in-difference analysis is petty. Stop the denial.
They are only a few pixels in size to begin with. They start at about 8 pixels and go down to 2 pixels (If I remember correctly). That's one quarter of the original size. If you want the difference to be more than a few pixels, use a higher resolution photo.
Those aren't the details we are talking about and you know it. With the sun and moon, we can see distinct interior details.
What's the difference between interior or exterior details? They are details. We've seen that it the magnification effect can also change color depending on the light source, too.
With the moon, we can take clear high resolution shots showing craters, valleys, "maria", etc. We can see a distinct, sharp edge.
With the sun, we can take clear high resolution shots showing sunspots and flares. We can see a distinct, sharp edge.
With these pictures of glare, there are no interior details. There is no distinct edge. All you can do is say "Eh, it's sort of not perfectly circular..."
If you can't tell the difference between these two scenarios, I honestly don't know what to tell you.
