Hi r11911177,
Why a poll?
I have tried any possible way, I get good results with it.
Set your object in an environment, e.g., a Sky object with an HDR. Render then in the Picture Viewer.
The Interactive Render Region is for preview, do not rely on that too much. The Interactive Render Region shown in your picture has its quality set to “half” and is not expected to render anything close to final. It is a fast preview, nothing else.

If you have a question, please share the scene/project file while the setup content is reduced to the problem. Images do not help a lot. I can’t even see your object manager, nor any rendering that would count.
All the best
