The new Boll ALC blades have the green hologram dot and also a new print on the blade face. The 2017 Butterfly catalogue shows the new printed design below. I've seen one of the new ALC blades with this design and the green dot.
Here's a link to the catalogue also if anyone is interested - https://issuu.com/butterfly.tt/docs/katalog_2017_mit_preis_en_web
