What does Blooming mean?
Blooming is visible glow around a bright object in an otherwise darker area, often associated with backlight zones larger than the object. It is a display interaction rather than automatic evidence of damaged video data.
Why it matters
Captions, stars and bright interface icons can make the effect obvious. Viewing angle, local-dimming mode and panel behaviour influence its appearance, and phone cameras can exaggerate it. Changing the subtitle style may reduce the contrast demand where supported, but accessibility should remain the priority. Disabling needed captions merely to improve a black-screen photograph is not a useful everyday solution.
A practical example
If a white subtitle produces a halo that follows it across different sources, compare the television’s supported dimming settings and view from the normal seat. Do not expect a new subscription password or a higher source resolution to remove the panel’s physical backlight behaviour.
