“ Although the difference is unlikely to be visible in most instances, it's interesting to see that the Sony A7R II actually beats both its successor and the D850 for Color Sensitivity for much of its sensitivity range. However, at around ISO 1600, the color sensitivity of the D850 and A7R III drops to around 20 bits. As the ISO is pushed above this value, color sensitivity continues to drop, and it will become increasingly difficult to reduce the visibility of noise without reducing color saturation when processing raw files. The A7R II sensor copes a little better, not crossing the 20-bit threshold for about another 0.7 EV. „
