Not sure I get it.
FWIW I have wondered the same thing. I have had times where the light flash, but I haven't been able to discern any distortion from clipping. Likewise, if I run material into Izotope RX4 (which has a cool function to repair clipping), I can see cases that sure look like they are clipped, but I can't hear any distortion.
I have just attributed this to:
1) the software saving a little headroom before clipping actually occurs
2) light clipping being hard to hear.
If you want to be really safe, put the Concrete Limiter on each track.
