Alright, Thank you Miki,
I have also made a bit research my self, and a clear answer is missing.
But for gaming I need to choose Bitstream for Surround when going through TV, which is like that on all devices not only B&O.
And Bitstream should be as good, or at least 99% as good.
So far so good.
But when I will play a Blu-ray Disc (Which is rare) It only output in 2.0, even if I change the output for bitstream on the PS5(A menu only available when you play a Disc)
In the sound information on the Harmony it is saying that the PS5 output PCM even though I choose Bitstream so the problem is the PS5
I will try to dig further, but if anyone have found a solution that works let me hear :)
