No, i decreased it, because this has no influence to the VU movement. Only increasing the Input signal from outside has influence to the movement of the VU. Nothing else.
So increasing the input signal, by implementing a headphone amp (to increase the inputsignal MUCH more) now I am able to have the same VU movement, as before the update. Everything is o.k. now.

However I am happy to find (for me) a solution for that strange update.

Yes, the VU meter show the actual input level. So if it's not moving much it's because the input level is too low. I guess you found out about that

On my Ultra all inputs make the VU meter move close to 0 dB. This is actually not correct if you look at what scale is used but if it's only for looking at something moving it works fine for me.

What about if you stream from the WiiM? Do you see same issue?

@WiiM Team said they will change the minimum of the scale, so maybe that will resolve your request for needle movements?

No, streaming with the WIIM shows normal movements. Thats fine.
Only the Line In is working different comparing to before the update.

Of course I would like to remove the extra headphone amp again out of my chain.
So if they would change it back to what it was before, or as you wrote "change the minimum of the scale"I would be very happy.

Was the only reason to add the headphone amp to change the appearance of the VU meter?

Yes. I am always looking for solutions, if something goes wrong.
