I's very easy - in DreamWear, nothing is inserted into the nostril. DreamWear is nasal mask (not pillows) exactly in the same way as Amara View is 100% full face mask (not full face hybrid as RespCare or Mirage Liberty). The type of the mask is always written in the description and on the bag, so it's nothing to argue about.
in your faulty understanding of the situation, you've neglected one simple yet crucial element.
resmed makes the definitions of what resmed machines call nasal/pillow/ffm, and a wholly different, unaffiliiated company is making the dreamware, and putting whatever they want on the package.
ASSuming that respiorincs is naming their product so that it properly aligns with resmed definitions is foolish.
Respironics puts a X number on their masks, resmed doesn't.
it has nothing to do with whether the mask has a centering cone.
and nasal pillow masks don't "insert into the nostril", if you want something that inserts into the nostrils, then look at a wholly different class of masks called "nasal prong" masks.
however, since you have no understanding whatsoever about the function of the system one resistance control value, OR the function of the mask fit settings on a resmed machine, it doesn't really matter.
