Umm, not to be a nit-picker but comparing phone camera photos of TV screens is a bit pointless.
The (phone) camera adjusts contrast, color temperature, dynamic range, and more dynamically.
If you really want to judge using photos, shoot with a camera that lets you lock down all parameters, shoot in raw, edit that raw with the same develop settings in a software.
For example, if the C1 oled is brighter or more contrast-y than the FALD panel, the camera will compensate by crushing the highlights or flattening the contrast respectively.
