well, i've grown just a reg dieff and seen var hybrids and i've seen many many foliage anthuriums too, though they're very diverse, but i know the growing habit at least.
so i examined this one very carefully, it's not the trick of light, it's definitely glaucous (i think that's the term?) and it has a cane as i said: shoudda taken a better pic of it, but i do have a not-so-good pic. at least you can see it's a dieff cane.
mj, what do you think of other pics of d. oerstedii that they show if you google - why they are so different ? or are they incorrect?
