if (igt_pipe_obj_get_prop(IGT_CRTC_GAMMA_LUT_SIZE)) {
lut_size = igt_pipe_get_prop(IGT_CRTC_GAMMA_LUT_SIZE)
etc?

And call igt_pipe_replace_prop_blob() with IGT_CRTC_GAMMA_LUT instead, it will be committed on next igt_display_commit2()

Same here. We're trying to keep out the legacy crap where possible. :)
Hm, is the igt_display_commit2() at the end needed, or could it be an igt_display_reset at the start?
If you can't put in a reset, then igt_pipe_replace_prop_blob(IGT_CRTC_GAMMA_LUT, NULL, 0)
