If the file was available I could provide a more direct approach to trying to solve the problem but from looking at your screenshot of Blender perhaps the following might solve your problem.
I noticed you have Space Reflection on in Blender. Not a bad thing for Blender EEVEE but it will give you a false sense that those reflections in your scene will appear in V3D.
To achieve a metallic look in a shader you have a few options:
You can use a Principle BSDF Shader, crank up the metallic setting, and pull back on the roughness. Initially, this may not look right. To complete this approach you will need to add a texture to your World Shader. Typically an environment map. This map will be reflected in your metal surfaces.
However, your scene is of a room and you may want the room to reflect in your objects. In this case, you will want to set up a light probe in Blender with a reflection cube map. See the LightProbe example in the Asset Store. You can update it to 4.5 and see how that works.
A third option is to use the Post-Process effect in V3D and assign your object material to the postprocess effect. Not as nice a light probe but can work in some situations.
