My first thought is to ask what kelvin the LED ceiling lighting is. From the photo it looks very cool. Perhaps you can adjust to the 2600 kelvin which is warmer light. Most new LED fixtures can be adjusted to 3 different settings on the light and it would cost $0. Painting the walls the same color as the cabinets would be a sleek look. I would lean into the creams and whites so that your beautiful book matched stone is the star. Add warmth with what goes on the counter. A few minor changes and you will love your kitchen.
