The current schedule meets the early afternoon longhaul departures (like India) but there is a ~10am bank with a bunch of other connections, including Central Europe, ME and North Africa.
UA briefly tried DEN-FRA (or was it MUC?) then pulled out. I honestly don't see two widebodies-worth of demand to FRA (even with connecting pax). Maybe only in the summer; and, yes, an earlier departure ex-DEN would be fabulous. The current LH schedule typically means I wouldn't reach ARN until 6/7pm, and I still have 4-5 hours of travel after that. (It's also why I avoid BA's DEN-LHR unless it's significantly cheaper.)
