An X-T30 RAF shot in Acros embeds a black-and-white camera JPEG, so the
per-file look fits only the tone curve, and the colour came from the
neutral "camera RGB ~ sRGB" fallback: a grey sky and muted colours. The
raw decode (lossless compressed) was correct.
Add a hand-kept SAME_SENSOR alias list next to the generated
rawtoaces-data table: the 26.1 MP X-Trans CMOS 4 bodies (X-T30, X-T30 II,
X-Pro3, X100V, X-S10, X-E4) use the X-T3's measured matrices, and their
white balance reads in Kelvin through them.
