Actually from looking at a few DLX decks I have right here now, they only have the I to IV stamp and no dot.
The older DLX boards and even some new ones still have only the dot, as do a few other brands here, including Baker, DGK, Element (which also have the laser info over the dot area) along with two others I know are BBS that don't have anything on the tops.
Most of the still sealed in shrink decks have the dot under the warning sticker, so it is often not noticed until you take off the shrink and sticker, which I always do before gripping.
