To be honest, I can't see the differences when downsampled CbCr at all.

As noted in an earlier slide, humans are less sensitive to chromaticity than luminance. We can see this in the downsampled comparison of luma vs CbCr channels; we can see a stark difference in quality when we downsample luma channels, but hardly notice any difference when downsampling CbCr channels. Following, it makes sense to compress the CbCr channels in order to decrease memory usage but preserve quality
