iPhone 17 Pro Max: Scores Apple-published 3,000-nit outdoor peak brightness, 460 ppi and adaptive refresh up to 120Hz. Peak brightness is not independently measured.
OnePlus 15: The UK specification publishes 1,800 nits in high-brightness mode, while launch wording calls it peak brightness. These measurement labels are not interchangeable, so v1 peak-brightness scoring is withheld. Verified pixel density and refresh limits remain visible.
