 The camera sensors are always RGB and linear. Generally, those values get converted to YUV in the files that are produced, because it is a more efficient format thanks to chroma subsampling, and produces smaller files (even if of lower quality, i.e. you lose part of the colors data). The conversion is nonlinear and so it concerns the "transfer characteristic" or gamma. The encoder gets input YUV and compresses that. It stores the transfer function as metadata if provided.
