-ARW, NEF, RW2, RAF, CR3, CR2, PEF, SRW and ORF decoding supply sensor data and camera white-balance multipliers, but currently no measured camera colour matrix. Treating camera RGB as linear sRGB produces a dark, muted default rendering. The loader now estimates a file-local starting look from that file's embedded camera JPEG, only when a usable camera matrix is absent. All output pixels still come from the RAW sensor data; there is no JPEG replacement or uniform saturation boost.
