Whow can I create the perfect sound bubble?

[Stefan H.]

I use a 7.2.4 sound system with my Denon AVRX3600H.
I'm struggling with the surround and Atmos Speaker to create a perfect sound bubble on the MLP.
For me it's like the sound of the speaker "glued" to them. I miss the Spatiality.
What can I do?

hard to imagine 7.2.4 sound system not sounding like a sound bubble with proper source material, but maybe it's not well calibrated, or placed?

My system is well leveled, but not perfect placed surround. Also the Atmos are not in the perfect place. But this are the bounderies of the room.
I guess I need something like virtually moving the speaker in the perfect place.
Any ideas? How to do this?
Is it manually possible?
