Well, I bought the Blu-ray disc of the Live in Prague performance. No, the sound is not treble heavy but really bass heavy, with track No. 32 as the heaviest.\nStreaming will never come close to the real disc. Very well organized performance with excellent musicians, singers and choir.\n\nI don't have Atmos speakers in my system. The disc plays as a 5 channel recording with a lot of signal coming out of the left and right surround speakers as well. If you want to play loud, you need to have good subs that can take the power, very possibly some at infrasonic frequencies. It's a damn good disc if you want to annoy neighbors.
