Also, you should really have an iterative process for this. Don’t put all your maps in the material, if it looks bad you won’t know why. Start with the base color and use constant values make sense for roughness and metallic (0.1 roughness, 1 metallic is going to look a lot like your reference image). Ignore AO as well.
If it does look like the reference, check with the metalness map instead of the constant value, etc.
