I think it will make the car look dated if you go for stark color blocking like that.
I would play with adding piping instead to go with your black/white shifter motif. Like they do it on the Range Rover, piping on the edges only.
I would also maybe replace the black carpeting on the doors and foot wells with dark grey/alcantara, do the steering wheel in alcantara with padding, and find similar shade of grey for the floor matts. Could work on the seat inserts too since it will be softer blend than going full on white. So you have a "theme" of white/black/grey with hints of white stripes here and there.
piping in black interior (not a fan of the inserts though).
