It looks like HiFiBerry was leaving a significant bit out of their advertising for this board, I don't remember seeing any mention of forcing all digital outputs to a single sample rate. In fact this page https://www.hifiberry.com/docs/data-sheets/datasheet-dac-dsp/ says "Sample rates 44.1-192kHz". That feels to me like misleading, or false, advertising. When my board eventually turns up I'll see how much I like it, or whether it's heading for eBay....
