Enemy Killer Indicator Inconsitency

What I am speaking about is that red box and silhouette that appears when you get killed (sometimes), Heretofore referred to as "Indicator".

I find it to be inconsistent. I don't always get an indication of where I was killed from. I may just not have a full understanding of what causes it, so forgive my ignorance. But it seems that the Indicator does not always appear. I don't know if distance affects this, class, or weapon attachments. Perhaps a suppressor removes this, referring to the description of a suppressor "removing information" or something like that (I don't recall the full description). The camera still points towards where I was killed from so I am not 100% sold on my theory about the suppressor. 

This part of my concern may be more "feedback" related, but the Indicator does sometimes make it quite difficult to see the enemy and/or ping them while downed to assist teammates in spotting them. The ping seems to prioritize the Indicator itself over the enemy that may be in that direction or "behind" the Indicator.
