So much, yes. The way her voice just slightly wavers. 
Morrigan's romance is recognized pretty well, but that was one of my favorite friendships in Bioware history, and there's no way for it to really be remembered in game.
Yeah...I've never actually done Morrigan's romance personally, as I've never actually completed the game with anything other than my Lelimancing female Mahariel, but I did watch it and...I dunno, it was well done, as all of the DAO romances are, but it just didn't feel quite as special as her coming to regard my Warden as a sister. The final scene at the gate, too, was one of the most impactful moments of the game for me, and strangely the romance equivalent just didn't feel like it had quite the same weight behind it.
W: "Then allow me to thank you now, for what you've done."
M: "You are
most welcome. I consider it the very least I can do. I knew nothing of friendship before we met...but I will
always consider you such. Live well, my friend. Live gloriously."
I could gush about this all day. At least she kind of speaks in a similar tone to those lines when she talks about how she wishes things ended differently between her and the Warden, but...more recognition would have been nice. Her coming to see someone as a sister is just as significant for someone like her as a romance is.
