Personally, I would worry more about blending conceptually with the work of the group of which I was a part (Isn't that what usually makes it a "group" in a well-curated show that is worth being a part of?), but if you feel that what you are doing makes a difference, have at it.
I don't like having my work up alongside cheap inferior trash either, but I see just as much cheap analog trash as cheap digital trash. There are no cheap trashy artistic media that alone devalue any other art based solely on its medium, but there are cheap trashy artists who devalue art in general. I'd worry more about being seen next to these types of artists than I'd worry about being seen next to any sort of specific art medium.
If you feel that the art of those around you devalues your own art, then do not participate in the show for that reason. Saying that it is for technical reasons alone is an easy way out of confronting the real issue, which is that you do not want to be devalued by being shown alongside those who you view as bad artists. Just come out and say it; you think your art is better, and/or you think that the curator is doing a bad job of selecting work that fits together in a group. Don't hide behind technique; you think your medium is better. One will sound arrogant either way, so might as well just speak the truth of the matter.
