Bloomberg says the supplier is Samsung.[0] Not entirely surprising because Sony is somewhat of a competitor and that only leaves LG who is not nearly as good at mobile oled which is one of Samsung's largest markets. This said I know eg. Apple uses multiple display suppliers for the iphone 14/15 base model so it could be the same here.
Sony isn't a supplier for a cheap OLEDs. LG, BOE, and other Chinese competitors are. Random game tend to have static HUD that is a risk for burn in. I imagine that Samsung OLED is a safe choice for game console thanks to Nintendo's verification.
Which other chinese suppliers besides BOE can achieve 1000 nits HDR 2? Even BOE can barely do that being they have been canceled from the iphone 15 supply chain due to their reliability. They were having issues with iphone 14 as well which was only
>800 nits max brightness (typical); 1200 nits peak brightness (HDR)[0]
