It depends for what position you are applying for. For a Solarwinds specific role I would see this as an advantage. For a general monitoring engineer position there should be some additional info on the SCP certification.
I agree, it really depends on the role you are going for. If it has a high dependency on SAM knowledge, then yes you'll stand out in the crowd. But if the job requires high network skills, then no it won't make much difference.
I have found though that if I go for a network engineer role and they have Solarwinds, then my Solarwinds experience will help set me apart from the other candidates (that's assuming the network skills were all the same between candidates).
