how do I get this sound - reverb starts after a second

Hi,

How do I get this sound after the piano stops playing?
You can hear reverb starts and raise and fall in the measure, like a curve.

My example - piano is FELT, soft setting and velocity, reverb 5 sec, predelay 133… Reverb sounds just plain and hold the same loudness the whole measure, totally dull.

What can I do with my piano do sound more like the reference track (first example on you tube) - this piano sounds clear.
Why do I have that white noise after the attack, how to make it sound like the first example?

Thanks,
