Material vs. SharedMaterial - difference in SETTING?

Just checking since I can't seem to find a definitive answer.

The difference between GETTING material vs sharedMaterial is obvious - the former creates a copy, the latter references the asset.

Is there any difference at all when SETTING / assigning the material? Like,

 public Material materialAsset;
 public MeshRenderer meshRendererA;
 public MeshRenderer meshRendererB;
 
 private void Start() {
     // assign material to renderer A 
     meshRendererA.material = materialAsset;
     // and now assign it to renderer B 
     meshRendererB.sharedMaterial = materialAsset;
 }

Will there be any difference between the two?

Away from my work computer atm, hence unable to check myself.

Thanks!
