Oh, hells, no, Harry:
That thar critter is reflowable. :-)
We format the books to appear at a certain "portal" (view window) size. It's fixed in aspect ratio. We embed the background images (effectively, the pages themselves, so to speak) nearly triple the size of a standard Fire device, and big enough to look crisp on an HD. The 1:1.6 or thereabouts aspect ratio never varies from page-to-page, or from one device to the next. If the book is placed on a slightly different device--say, K4iOS, the aspect ratio remains the same, and the margin is displayed in black or black/grey, around any empty bits.
Each block of text (ideally. I don't know what other folks do) has a RM box or pop-up. This is what enables a FXL book to be read on a small device--that the text is itself enlarged. The reader swipes from r-to-l to advance from one pop-up box to the next, and proceeds through the book.
As I (hope I) said previously, I've never seen this creature, that reflows. But I'm not going to say I've never heard (seen) someone talk about it. They have said or claimed that text inside the boxes changes, depending on what device it's viewed upon. I can't, for the life of me, imagine how that works, but that doesn't mean it's impossible.
So, in FXL, for *each platform* (as an "FXL ePUB" one ring type thing doesn't really work, either) functions as to "one ring to rule them all." An FXL mobi for Amazon is viewable on all Fires, Paperwhite, voyage (I believe); K4PC, K4Mac (?). Also K4iOS. I don't honestly know if the cloud viewer reads FXL MOBIs.
Ditto FXL ePUB for iBooks: works for all sizes of iPad and iPhones.
ePIB format for B&N is limited, to solely working on the color HD Nooks. Hardly surprising.
