The observable universe is of finite mass and size, while the total universe is of infinite or finite mass and size. On a macro scale, the total universe probably looks similar. It's definitely not micro homogeneous or entropy would be infinite and heat death would have already occurred. Heat death won't be the biggest problem because of the likelihood of the Big Rip.
