In library I work on I've set precision such as converting `lab(100% 0 0)` to XYZ would give me exactly value of D50 (`[0.96422, 1, 0.82521]`) and converting `rgb(100% 100% 100%)` to XYZ would give me exactly value of D65 (`[0.95047, 1, 1.08883]`)* and this alone solved all conversion inconsistencies I had.

*I've normalized D65 to have same precision as D50
