When taking a Screenshot for Realm Stories, simulation and Render distance both decrease.
Notice in the video the fog goes out about 12 chunks from where it was during the screenshot.

Do you mean that the screenshot that shows within Realms Stories does not match what you had on-screen, or are do you mean only that the fog appears to go in and come out as shown in your video? The latter is probably intended based on MCPE-158525.
