How bright do these OLEDs get in a sunny room?

Brightness has been the headline upgrade for 2025 OLEDs. RTINGS and mainstream tech press both flag the LG G5 and Sony Bravia 8 II as the brightest models in this group, with the C5 and S90F a tier below but still usable in bright rooms. The entry-level LG B5 is the dimmest of the group and is better suited to controlled lighting.
