Because it’s a real photo which is hard to process in such a short time. A PS fake could have been done in advance and would look perfect. Check this guy‘s timeline, he’s a gifted solar photographer.
Processing usually involves combining images of different exposure time or to reduce noise. You don’t make a picture like that with a single click on the exposure button. But this is accepted image manipulation. Combining images of totally different contexts without telling so is not.
(Explaining, not accusing)
The white "border" around the edges of the sun looks similar to a bad green screen effect, or when you cutout and paste an image in photoshoot with blurry edges. In this case, the edges seem to be caused by solar flares, light bending, and maybe some lens flair artifacts.
I think being able to see that ring of solar flares around the surface of the sun is actually a sign of a really clear and well-focused image. Ironically we're not used to seeing that edge with such clarity, and the closest reference point we have for unexpected thin bright edges are bad photoshops.
When I got up this morning I noticed the sunlight didn't seem... right. Then I remembered. It's amazing how sensitive we are to sunlight. I can see how such events must have terrified people.

I'll never forger seeing a solar prominence with my naked eyes during the 2017 eclipse.
