CLI, palette information from PGC VTS_01_0.IFO?

[Anime]

the only program i know so far can CLI out a palette is subrip
but i cannot find command to stop loading BMP, example i just want the SST CLUT info...
And recently i found that subrip give the wrong color info on random color if fetching from IFO, which is too much difference for non-simple color given by pgcedit

st_format 2
Display_Start non_forced
TV_Type NTSC
Tape_Type NON_DROP
Pixel_Area (0 477)
Display_Area (0 2 719 479)
E2 (255 0 0 ===)
E1 (0 0 0 ===)
PA (0 0 255 ===)
BG (255 255 255 ===)
Directory D:\Tools\SubRip
