Our Verdict
LG B2 OLED
LG OLED Flex
The LG OLED Flex and the LG B2 OLED are very similar TVs, minus the Flex's ability to curve. The Flex gets slightly brighter in HDR, so bright highlights pop more. It also has much better PQ EOTF Tracking, so brightness levels are as they should be in HDR. However, the B2 is much more color accurate than the Flex. However, SDR is also a bit brighter on the B2, so if you mostly watch SDR content, this is something you should consider.
