Of course at high rpms the fricitional losses are significantly higher than at lower rpms.
The big variable is enrichment, some manufacturesr richen the mixture at high load/low speed, others stay at Lambda1, richening up by about 10% (from Lambda1) gains about 5% more power, so a loss of efficiency of 5%, but if it stays at Lambda1, then yes its more efficient at wide open throttle than a light load.
