My television's white-balance/color temp controls don't perform well enough to allow me to get my grayscale to reach D65 without significant (gamma and/or chromaticity) error. So, short of new hardware, I am forced to compromise. I believe there are four ways to compromise (i.e., a workflow approach) as follows:
1. Minimize gamma error at the expense of chromaticity.
2. Minimize chromaticity error at the expense of gamma.
3. Seek and accept some amount of error in both gamma and chromaticity that is neither minimal for either but represents some semblance of "error balance".
4. Perhaps controversially/illegitimately "calibrate" to a slightly higher white point. HCFR software currently allows this to be done rather easily.
So a couple of questions follow:
1. Which compromise above is best in your opinion and why?
2. I know the formula for finding out the x and y coordinates of a different white point on the daytime locus. So if, hypothetically and potentially against the advice of the community I nevertheless choose option 4, would the coordinates for the primary colors (RGB) need to also change from the sRGB/Rec709 coordinates? And, if so, where is the formula for backing in to the alternate RGB coordinates based on a manually chosen white point?
