Yes, of course higher level of hemoglobin and myoglobin is nice for apnea (or for living in high altitudes), but I do not think it would make any difference between dry and wet apnea.

The role of myoglobin as a store of O2 is supported by the observation that diving mammals and birds can have muscle myoglobin contents that are increased 10- to 30-fold compared with those seen in animals that do not experience prolonged apnea
