[Avid-L2] Default BCC 8 Unsharpmask raises video level slightly?

 

Mac OS 10.10.5. MC 8.9.4 BCC 8.X(the one from Avid site).  I noticed today that when I apply a BCC 8 UnsharpMask with default parameters the video level of the shot jumps up very slightly.  It's mostly noticeable on the black level going up a few millivolts.  The parameters are default with a radius of 1.  Setting radius to 0 makes the level jump go away.  Higher values bring the level up a bit more. 

I'm pretty sure I"ve seen this before but can't remember if it only happens in 4K projects.  It's not severe enough to not use the effect but I'm wondering what is causing the overall level to rise on the scope and in my monitor.  Clearly the bigger the radius the more noise is added to the edges with large numbers creating ringing on video transition areas of the image.  I get the ringing just not the slight bounce in level.  It's not like full range vs. legal level but wondering if anyone else has noticed this?
