The image that you have shared is the most upto date variant of the killfeed UI effect.
You may have noticed that within the maps trailer that we had shared a couple of days ago, there are differences in UI. This is down to the nature of video production, these trailers take a bit of time to put together and while that is going on the game is always in development up until the moment that it is not.
So you may see some things that we've shared beforehand (such as the video footage like the image above shows) which will appear at launch, whereas some things are dated as they were filmed before these UI changes.
