Dead pixels have a particular look which this does not seem to me to have

I don’t think so myself. Dead pixels tend to be single pixels and remain one specific color

My guess would be that there's some dust stuck in there.

If it's dust there's really no fix for it, as you would need to take apart the whole monitor and doing that risks that even more dust goes inside.
