I got this charger with a new, sealed phone from official distribution and it has plain QR code (dots are not separated) and the house icon is rectangular. I'm afraid you've got yourself two fake chargers...
If the jack is skewed (not perfectly aligned) this is a sign for non-authenticity. However. for a better judgement, you need to check all the elements we've described in the video
3:30 & 4:16Here the position is reversed. The one on the right is fake, the one on the left is real. I compared it with the original charger of my mobile, the left one is real and the right one is fake.
