Is there a reliable way to tell if it's QD versus woled?

Looking at the QN65S90DDFXZA at Costco - I read the info about panel lottery and wasn't 100% certain if the FXZA was a surefire way to tell if the panel was QD.

I missed the C4 last week at $1399, considering the Bravia 7 at $999.97, but the S90D is pretty tempting at $1299 if it's actually the QD display.
