Skin pigmentation and figurines at Knole House in Kent

At some National Trust properties, figurines with dark skin pigmentation, such as the one on the left (first picture), are labelled with an apologetic warning that the figurine depicts a person of colour in a demeaning pose. Not so in Knole House, near Sevenoaks in Kent. In the same room, also without a label, there is a figurine depicting a person with pale skin in the same demeaning pose.
