Using DDP only works with fixed colors

Hi, i setup DDP with a single bulp (Athom, PWM RGB+CCT) - but that only woks with simple palette like color1. With other palettes like Aurora2 i have this palette only on the sending controller. The receiving bulp only shows the fixed color on boot time (this orange like).

I expected that DDP sends RGB(W) values in realtime or do i need to setup something to make this work?

Thanks,

Tom
