We are running into a situation where the insulation is slightly under the R38 (R34.8) that is required per ASHRAE 90.1 yet the energy model shows we are over 10% energy efficient. Will this still meet the LEED v4 requirement?

Yes. The insulation value is a prescriptive measure so it is available for trade off.
