DFW doesn't go 777 until March, so if you're flying in Jan, then compare it against A380 old style Club World

And side tracking, but looking at the April 25 seat map, it looks like it's a 3-class 777 servicing DFW. So from 14F, down to 0F

EDIT: It's 4 class 777 (8F) for November/December, but then reverts to A380 for Jan/Feb/March, then 3 class 777 from April. At least that's what it looks like now
