I have now tested the Hornby decoder with SPROG.

Writes are OK in direct and paged mode.

Reads do not work correctly in any mode - confirmed by more than just a rumour that this decoder does not support readback in order to save money (apparently DCC supplies are exchanging them for Lenz decoders). Strangely, direct bit verifies are ACKed for every bit regardless of the value of the bit in the CV. This makes it appear that something is happening as the motor pulses but the results are meaningless.

The functions work OK. Directional outputs switch correctly with zero speed packets so you can change directional lighting with the loco stationary.

Motor control seemed a bit rough but I was using a VERY cheap motor.
