Let me rephrase the question – Do we call the Visible Spectrum that because that’s what we can see or is there something different about that part of electromagnetic spectrum (ES) that allow vision to occur. Alternately, If light is dual in nature, being both a wave and a particle, is that the same for other parts of the ES?
Which brings me to the question that I’m most curious about; would it be possible for a creature exist that can see, the same way we see, but using frequencies from other areas of the ES?

All electromagnetic radiation is the same phenomena. There’s nothing special about visual light. It’s just what our eyes are adapted to see of the entire spectrum. Light isn’t dual in nature. Light is light and we just don’t have a good explanation for it currently and depending on the specifics it’s sometimes preferable to talk about it as either a wave or a particle but light is its own thing.
The answer to your question is yes. As long as the creature in question has some kind of sensory adaptation for a specific frequency of electromagnetic radiation then they will sense it. Technically you can sense infra red light. That’s why you feel hot on a sunny day or infant of a fire. Heat is just infrared light.
