Three secret clues hide in the Note 7 event invitation. Can you spot more?

A couple of days ago, Samsung sent off its official invitations for an August 2nd event — one, where the spotlights will shine over the new Galaxy Note phablet – one of the most recognizable and loved line of large-screened smartphones out there. Like most smartphone fans — we are eager to see what's in store, and are over-analyzing and over-thinking every little clue, the invitation included. Join us as we speculate over this card!

A reveal of the color options?
Looking at the whole picture again, we also noticed that there are only three colors to the whole theme. Sure, this could be for the purpose of minimalistic appearance, but do note that the colors are black, blue, and white. Coincidentally, a recent leak of alleged official Note 7 renders revealed three finishes for the new model – black, blue, and silver. Unfortunately, this may just be a confirmation that there won't be any fancy colors like gold or pink rose gold — at least not at launch.

A nod at the iris scanner
Why the choice for the odd circle shape to the left? Is it a loading circle? We certainly hope not — everyone hates seeing these. As we glared and gawked, we thought “Huh... it kind of looks like an eye...”. Especially with the little white strip on the bottom-right, which could easily mimic the light reflecting off of a blue-eyed person's iris, we can't help but think that this is a definite nod at the Note 7's iris scanner lock. We've seen so many leaks of the scanner, including its software side, that this is more of a fun reaffirmation, than a curious mystery. Sorry, Samsung.
And with that, we are spent. Can you pick up on any more clues from this Unpacked 2016 invitation?
