Is this a ripoff, Honda HRV 2016 Differential Fluid Change

Had a 2009 Nissan Frontier that the dealer said required several different fluid and filter changes along with minor “checks” and adjustments. The estimate was for only $925. Took the truck to my friendly local mechanic,showed him the estimate,and then watched him do it step by step for $225.
I no longer bring any vehicles back to the dealership for anything but “free” maintenance or warranty work. I prefer to make my own boat payments,not the dealers.
