Not sure DFW is A380 capable/accredited, memory is faded a bit but the everything needs widening to prevent FOD to the outboard engines and there are other issues with passenger egress etc.
DFW's International terminal D is set up for A380s. The only question was with the freighter versions, the bridges are only rated to 1.25 million pounds so a full freighter would have to stay on which ever side of the airport it was loaded on.
