Check the account’s actual tier
The current international privilege page describes Standard quality up to 1080p and Premium also offering 4K where supported. Confirm the tier shown for the account on the viewing device. A receipt, account badge and actual player must refer to the same identity for this comparison.
Do not buy Premium again because one episode lacks a 4K option. First distinguish an inactive or different account from an active tier whose selected content does not supply that presentation. The remedy depends on which of those observations is true.
Inspect the exact programme and playback page
The official qualification says some titles may not support certain stream qualities because of rights and directs viewers to the quality shown on the playback page. Use the specific film, season and episode rather than a series-wide promotional cover.
If another episode offers a higher quality, retain that comparison without generalising it to the whole catalogue. An available language or alternate cut can be a different supplied edition. Confirm that you are comparing the same item before interpreting the difference as a device failure.
Confirm the supported viewing route
The privilege page also limits these quality features to selected devices. Check the current official application and supported route for the screen in use. A panel’s advertised resolution is a hardware specification, not a guarantee about every service app or title delivered to it.
For support, provide the tier, item, device, app version and quality choices actually displayed. Explain whether the higher option is absent or selected but the picture seems poor; these are different questions. Avoid claiming a measured bitrate or tested resolution from the mere presence of a 4K logo or a Premium plan description.
