I find without first neutralizing any residual color casts, tends to deaden my image from the outset.
Case in point: Your original image is in the upper left triangle where the whites have a definite color cast of yellow and mine in the lower right where the whites have been "neutralized" so when I do set the white point it is based on a true white.
Maybe I am all wet behind the ears on this...
