OP mentions a ten hour flight, but doesn't say anything about a second meal service (aka pre-arrival snack or breakfast).

If it was a ten hour flight, could it have been marketed as FC rather than D1, but flown on an aircraft having a D1 cabin with flat beds?

Ten hours is making me guess ATL-HNL, which is marketed as domestic D1.
