You are quite correct. Pope Francis specifically asked Justin Welby, the Archbishop of Canterbury, to bless him – something he does not do when a layman visits him.
The photo of the Pope, bowing to receive the Archbishop’s blessing:

Here you will find the Pope’s address to “His Grace the Archbishop of Canterbury and his entourage.”

His Holiness concluded their conversation by adding: “Your Grace, I thank you once more for your visit. I ask the Lord to shower his blessings on your ministry and to sustain you and your loved ones in joy and peace. Amen.”
This was the second meeting between the Pope and the Archbishop of Canterbury. Their first meeting was in 2013 and the speech of the Pope may be found here:

I would particularly highlight this passage, which was very memorable:
*Your Grace, Dear Friends,
On the happy occasion of our first meeting, I make my own the words of Pope Paul VI, when he addressed Archbishop Michael Ramsey during his historic visit in 1966: “Your steps have not brought you to a foreign dwelling … we are pleased to open the doors to you, and with the doors, our heart, pleased and honoured as we are … to welcome you ‘not as a guest or a stranger, but as a fellow citizen of the Saints and the Family of God’” (cf. Eph 2:19-20).
I know that during Your Grace’s installation in Canterbury Cathedral you remembered in prayer the new Bishop of Rome. I am deeply grateful to you – and since we began our respective ministries within days of each other, I think we will always have a particular reason to support one another in prayer.
/…/
I am grateful, too, for the sincere efforts the Church of England has made to understand the reasons that led my Predecessor, Benedict XVI, to provide a canonical structure able to respond to the wishes of those groups of Anglicans who have asked to be received collectively into the Catholic Church: I am sure this will enable the spiritual, liturgical and pastoral traditions that form the Anglican patrimony to be better known and appreciated in the Catholic world.
Today’s meeting, my dear brother, is an opportunity to remind ourselves that the search for unity among Christians is prompted not by practical considerations, but by the will of the Lord Jesus Christ himself, who made us his brothers and sisters, children of the One Father. Hence the prayer that we make today is of fundamental importance.*
