Unpopular opinion: I think the Hubble images get way more credit than they deserve for showing us what space 'really' looks like.
I just read a fact in an article from the European Space Agency's website that said the famous Pillars of Creation image uses colors mapped to specific elements, like sulfur and hydrogen, which means the vibrant blues and golds aren't what our eyes would see at all, and that kind of changes the whole 'window to the universe' idea for me.
