Are both sectors showing the same seat map?
It doesn't look like any layout I've seen on an EK 777 before as most have Rows 6 and 7 in a mini cabin, then a galley and toilets, then Rows 8 to 11 in another cabin.
However, IAH to DXB has been consistently getting flown by the aircraft with the new J seats recently (there only are about 8 of them). It looks like you'll be on one of these, which is good, but I've never read or heard about a new layout as you describe on these.
