My Dakar is not a sport or an M but a customer ordered individual model ( and as far as i know still the only individual Dakar on the forum as the rest are either 1.9 2.2 or 3.0 sports or M roadster or M coupe) and it has the same individual sticker on the opposite side to the chassis number one.
But my Orinoco green is a factory built late made pre face-lift individual model so it also has individual sticker but different from the dakar as doesn't say colour on it.
And yes the colour stickers on the strut turret refer to body main colour in your case pistachio green metallic and the smaller one is the engine bay and boot inners colour pearl beige.
What you find with this inner and outer colour list is there are varieties depending on age and colour
As an example my 2 non metallic zeds
one pre face-lift and one face-lift both same colour on sticker so the dakars says Dakar yellow twice outside is gloss finish but inner wing same as youes that sort of satin sheen.
Metallics can get more complicated and the inner wing colour can be more dependent on the outside colour but if the 2 are the same for example
On the Arctic silver the 2 look the same but they aren't.
The exterior is Arctic silver metallic
The underbonnet is Arctic silver ( non metallic) so looks different from exterior.
My Orinoco is being a 98 on model T reg last of the pre face-lift its a kind of hybrid model and has a lined roof and multistage airbag face-lift seat frames a tu Euro 3 spec engine in a Euro 2 car so also like a lot of the darker face-lift model engine bay it is Schwarz ( black)
Even the colour stickers themselves aren't 100 per cent accurate as list mibe as Orinoco Metallic by mine is a proper pearlescent colour and has no metal just silica prisms
So the long and short of it is Bmw don't like to make it straightforward when then can just maje it complicated instead
