Could be a wrong info there on the Support page, or the product official page. If there are 2 variants of the screen, they would have to show the specs. They never mentioned anything regarding this nerfed display at the media briefing. And it doesn't make sense, why would the rest of the world get LTPO and in MY, SG & IN get non-LTPO?

Past models, with different screens come with different name, Pixel 8 Pro (LTPO), Pixel 8 (non-LTPO).

We still could get scammed though by G.
