Phil, I wasn't just referring to the blacks - I have no doubt they are stunning. I'm wondering how, say, medium to bright colors look, saturation levels etc in comparison - or put it this way - is there any aspect of the RS20 that the Lumis doesn't improve on?
I'm just looking for your objective observation as I've seen the RS20 but not the Lumis.
