Just bought the last grey Convoy S2 with the Luminus UV led from Simon’s store. No need for it of course. I already have two S2+ with Nichia UV leds. I’m excited to see what kind of difference there is between them. Wish I could have got two, so I can have one filtered with ZWB2 and one unfiltered like with my S2+’s… 
I’ll be sure to report my findings.
I am looking forward to hearing about it.
