In prints LPD 1+1 or 1+3 the tone change was subtle but noticeable.
It is dramatic if you do 1+10 or higher (warning, you maybe only able to develop a few prints so keep the stock handy to replenish)

However, when you tone the print the way it reacts can be dramatic
You get nice aubergine tones with selenium and dark chocolates or "caffe au lait) tones with viradon.
