Is a 4K webcam actually worth it over 1080p?

Reviewers are split. Streaming-focused outlets like StreamTechReviews argue 4K sensors deliver visibly sharper, less grainy 1080p output even when downsampled. Tom's Hardware, however, concluded the Logitech MX Brio is 'a good 4K webcam for a target audience that doesn't really need a 4K webcam' — most calling platforms cap streams well below 4K. The practical consensus: a larger 1/2" sensor and good HDR matter more than raw resolution.
