That's not how filters work. You made that up out of thin air. This is a common problem with most every HDR system, even the very best ones will have errors like this and the filter effect you're seeing here is that it enhanced the contrast between the lighter and darker rendered areas of the sky. The problem is the rendering that was cooked into the original and the tree is the classic test example for HDR accuracy and refinement. It may not be a huge difference in the original, but the data is there and the filter amplifies it. The end result is that if this issue is cooked into the original, it makes processing latitude, whether using simple filters, or using professional processing software, extremely limited, if not time consuming.
You're trying to fake technical talk. I'm a photographer, I do this every single day for a living and part of the problem with dealing critically with smartphones and trying to get improvements is that there are people online who act like they designed the phone and are being personally attacked and then lie about what's going on to cover for the company. It's weird as hell where the phone is a tool in some countries, to some people, while in other countries, the phone is your social score. The HDR processing screwed up, BFD. No need to make up transparent lies and excuses and pretend everyone else knows as little as you.
