Since the Hyrum First Ward is privately owned, I couldn't take pictures of the interior. However, I did find a video that has an interview with the (at that time) owner, and included some photos of the chapel.
One blog reader actually pointed out this recent article on the Hyrum First Ward: https://www.hjnews.com/news/local/family-hosts-community-at-converted-hyrum-chapel/article_4fe97bf8-227e-5cb9-b89e-b7270f82c805.html.
It appears that while the rest of the building has been heavily remodeled to house occupants, the chapel itself has only undergone minor changes.
