From the pictures and information provided it only looks like there is a small difference in the design of the hoppers and adjustment collars, so yes you do seem to pay allot extra for the branding, as you always do with Mahlkonig.
But as always the actual price will drop after a few months, so I'll expect the two grinders to be within a narrower price range down the line. However Anfim is the cheaper brand of the 3, so a price difference is to be expected.
K30 can be had for €1699 so it's actually cheaper then a normal K30, €300 cheaper than the air version, additional €1000 cheaper than the V2. However none of those prices are MRP, so the €1599 MRP is not the price we will end up paying.
