Render Distance on Realms is much lower than on Local World

Whenever I get onto my Realm world, the Render distance is much lower compared to when I'm playing on a local or offline world. In my video settings, the Render Distance is set to 20 chunks globally (on all worlds that I play on) yet I still notice a huge difference in how far I can see. This is happening on both my iPad and Windows 10.
