Distance changes how much of a screen each detail occupies in your vision. Moving closer makes pixels and compression easier to see; moving farther away can make HD and 4K look more similar. Screen size and eyesight also influence the result.
Compare at the distance you use
A television is normally watched from a fixed seat, while a phone is held much closer. Comparing their resolution labels without considering that difference is misleading. Use familiar material on the television and assess faces, lettering and moving objects from your usual position before changing the subscription or buying equipment.
Separate pixels from processing
Softness may come from a low-detail source, noise reduction, scaling or compression. A closer seat reveals all of them, not just the pixel grid. If menus look crisp but every programme is soft, check the source and picture processing. If menus are also blurred, check the output resolution and screen scaling.
Spend on the visible limitation
Try a good-quality sample at the same size and distance before paying for a higher display specification. If you cannot see extra detail from the seat you prefer, a better sound system, easier remote or improved room lighting may bring a more noticeable improvement to the way you watch.
