Share for Review is to quickly share a design that is still a work-in-progress with the Reviewer(s) for quick feedback. Since the review opens in a browser for the reviewer, it has to load quickly even on slow networks, that’s why the image quality has been kept low deliberately so that the page loads quickly without long wait times. Using high-res views will slow down the loading of pages in the browser considerably, marring the experience.
Hope this helps.
