its not exactly the same:
example for “famous canon colors”:
1: just color lookup table created by darktable chart
2: color lookup table with tonecurve created by darktable chart - similar to ooc jpeg
3: filmic adjusted to get a similar greyscale; preserve chrominance = no
4: filmic as 3 but preserve chrominance = rgb power
in case of 3, filmic + preserve chrominance = no, you can tweak the yellow tone by increasing output saturation about 10% in color balance, but then the blue tones are ways too saturated
For different picture styles different fine tunings needs to be done to get a result similar to ooc jpeg - manually instead of just using darktable chart to give you a decent style
