Help! with old white tazetta

Hi all,
 
Well, nothing like a new wild goose chase to keep one occupied.
Came across an old, all-white tazetta. It is blooming in Feb – way later than all the paperwhites, which were nicely frozen anyways, and with rounded petals, not pointy. The foliage is much more like Grand Primo than a paperwhite strain too.
ANY suggestions? No pale cup turning white – the half-opened florets’ cups were white.
Unfortunately, the only blurry shots i took were of it (!)(too embarassing to share), hope to get more next week.
