The big issue with that display was that it either stretched or windowboxed content randomly out of the blue for no reason, often if it detected any change in resolution.
Haven't had a chance to listen to the show yet, but The CW's Batwoman is using 2:1 aspect ratio, too. Looks absolutely horrible in those markets like Reno where most cable and satellite providers only offer that channel in letterboxed 4:3 standard def.
