Poor quality graphics in drawing views in the Drafting app

Hi community

I am looking for an expert to help me with the graphic and render settings for drawing views in the CATIA Drafting app. I am generating drawings that have multiple views on a sheet. The simple drawing views (with black lines) are ok. But when I am trying to add colors to these views based on the 3D component - it is not being applied in high quality.

It lacks depth, has jagged lines, washed out colors and is pixelated. Upon exporting in PNG, JPG, or PDF formats the view still has the same poor render quality.

For your reference I am attaching the comparison between my drawing view render and how It's supposed to look compared to the part color.

This is the poor quality isometric view on the sheet-

And this is the reference part-

To adjust the graphic settings I am using the Properties for the respective view that I want to edit and here are the settings that I currently have- 

Here are my settings for the "Options" option next to the view generation mode-

I hope someone can provide a valuable solution.

Thanks
