cam_xyz and rgb_cam not populated for X-T5 and X-T50 cameras

Submitted by 0x (not verified) on

Hello again Alex , these logs might help with the situation this happens for the RAF files that have this
matrices as so! but i see that in the source there is this line in the colordata.cpp

  { LIBRAW_CAMERAMAKER_Fujifilm, "X-T5", 0, 0,  // same CMs: X-T5 and X-T50
    { 11809,-5358,-1141,-4248,12164,2343,-514,1097,5848 } },

i am on this commit : HEAD is now at 3733457d imported 0.22-PreRC1

and this is what i get but shouldn't automatically these matrices be populated

also what is the relation between cam_xyz and rgb_cam? can we populate the rgb_cam from cam_xyz? i am asking does the data from colordata.cpp is the cam_xyz?

  { LIBRAW_CAMERAMAKER_Fujifilm, "X-T5", 0, 0,  // same CMs: X-T5 and X-T50
    { 11809,-5358,-1141,-4248,12164,2343,-514,1097,5848 } },

how does libraw knows what color_xyz shall be used ?
i tried to set use_camera_matrix with different values from 0 - 3 always same colors! so i might need some help here cause i got really confused . thanks.
