A:Answer Yes. All LG C2 panels have the OLED evo panel; hence the name and product description.
However, the brightness level for the 42" and 48" version is lower than the larger models of the C2.
From LG:
*OLED evo panel is brighter vs. the traditional WRGB OLED panel used in the B and A OLED series. OLED evo models are brighter than similarly sized, conventional LG OLED models, not including 42” or 48” C2.
