> would I be awestruck by how they see the world, how they perceive the color blue (to give an example), etc

Yeah another example I think about from time to time is our own sense of perspective. It's all relative, but my sense of how far away is "that thing over there" is probably different from yours. Partially because we may be different sizes and heights, but also because our eyes and brains process the world differently. Like a camera with different lenses.

Also, speed. If your brain's clock is faster than mine then you may perceive the world to be moving slower than I do.
