If they were to run some applications on the side it would validate the power usage. Like if it also was a Plex server it could be more reasonable to use more power.
Could also really hinge on the electricity cost for their region. At 10 cents a kwh and a delta of 100 watts we’d be talking 87 dollars a year assuming it’s always running at a delta of 100 watts.
I doubt there will be a 100 watt delta especially newer architectures that idle really well.
