While "max bpc" can be used to change the color depth, there was no way to check which one actually got used. While in theory the driver chooses the best/highest color depth within the max bpc setting a user might not be fully aware what his hardware is or isn't capable off. This is meant as a quick way to double check the setup. In the future, automatic color calibration for screens might also depend on this information being available.

There was no way to check which color format got actually used on a given monitor. To surely predict this, one must know the exact capabilities of the monitor, the GPU, and the connection used and what the default behaviour of the used driver is (e.g. amdgpu prefers YCbCr 4:4:4 while i915 prefers RGB). This property helps eliminating the guessing on this point. In the future, automatic color calibration for screens might also depend on this information being available.
