tv ui favors larger elements and longer transitions to make focus & change more legible for distant viewing. at 1m-3m people have a harder time following the ui. tv browsing is also much more frequently a group activity, where one person is pushing buttons and so knows what transition will happen, but others on the couch need to follow the activity too. different modality & ui priority compared to phone or desktop which are much closer to the face and much more personal/single player.
