If you shoot Raw, and are therefore able to take advantage of expose to the right (of the histogram) technique, then you need to read the LCD/histogram and blinkies.
They are both generated off the JPEG and so are affected by the camera's pre-sets. In particular, the contrast setting makes a big difference and you can push the exposure around a stop more if you turn the contrast right down, before the histogram/blinkies shows that the highlights are blown.
