It may be a colour specific to the manufacturer of the cabinetry. If you'd like it to match a paint colour exactly take one of the doors to a paint shop to be colour matched.

Dulux whisper white. Get a sample pot, paint a large piece of cardboard and see for yourself.

Don't go with white. While it is easy to replace door fronts and drawer fronts you won't be able to replace the tall vertical panels adjacent to the fridge recess and the microwave recess without pulling out half of your cabinetwork. If you went with a white you wouldn't be able to match the same white as these vertical panels, and the new white would look off next to the old white or vice versa! I'm afraid there is no easy solution that will make the new doors blend in with the old vertical panels, so I would go with a bold contrast colour block that looks good with the white vertical panels, as well as the black granite. Perhaps consider a Piet Mondrian inspired kitchen facelift, by introducing some black edging to the vertical cabinets and a careful composition of blocks of primary colours?

The front of your home looks like homes in Las Vegas, Nevada. Are you more interested in a bathroom along these aesthetics? In Australia the bathroom you have shown would be a very common look. If you are staying in the home for a length of time, and your budget meets your wishes. Then change it to whatever you would feel more comfortable with.
