Ah, actually if you're referring to a cello or violin, then most likely what you refer to as bloom is a more present midrange. Which can be measured. And can be added via a simple eq'ing

And to further confuse things re: this sense of space you speak of. If you're set on the fact that microphones can't pick up details that our ears can, then how could ANY recording capture a sense of space, since it's recorded using these dreaded microphones?
