I worried about a broken spoke and measured mine. I think the spokes for Vuelta are proprietary to their design so spokes might be only available from them. They never caused problems. You might take a good caliper and go find a set of these wheels and start measuring the spoke size for yourself.
This shows a close up of the hub and spokes. Given the other items in the picture such as the hub and flange, I can say that the spoke head isn't 4mm. I can't say with certainty whether the spokes are 2.6mm or 2.0mm at the head but they are
not 4mm thick. I can believe that the flattened portion is 4mm wide but not the head. And, as 2.6mm is a very uncommon diameter for spokes of any kind, I have a hard time believing that they use 2.6mm heads. 2mm, yes. Even 2.3 mm but not a heavy as you are stating.
And, as I'm very unlikely to buy a $350 wheelset that I would have
zero use for, I doubt that I'm likely to be able to measure one. If you have one and post a picture of the measurement, I'll agree but until I see the measurement, I'm still skeptical.
