MTX: My Problem with the new divergent char effect

Hi,

first of all, I love the new charakter effect but there is a litte gripe a have with it.
It looks way better on 2560x1600 than on 3840x2160.
I guess there is a fixed image in the backgoound. The bright part of this picture ruins it a little bit for me because it is to dominant and overwrites the rest of all other MTX. I have made some screenshot to compare both, fogive me my paint knowledge.

With other MTX that have some glowing effects, like eyes, or some detailed MTX, this bright part of the image is to dominant a overwrites everything unfortunately.

Is there a way to change that for me besides changing the resolution.
