I have finally had enough time to take some quick measurements of the Z95Bs internal speakers in my living room.
The TV is mounted on a wall mount.
Room measurements are as follows:
Width: 4.6m
Depth: 4.8m
MLP: 3.5m
Measurement chain:
Input: Windows PC->UMIK-1
Output: Windows PC HDMI-Out->Z95B HDMI 2 eARC
UMIK-1 is positioned at the Main Listening Position.
I was going to measure my Revel F36 with REW for reference, but although I was able to output sound from my Windows PC through the F36s, REW couldn't take measurements due to a sample rate error. I guess the problem in this case is my NAD C399s sampling rate. I had the PC, TV and amp connected via HDMI. No time for further troubleshooting.
I have applied 1/12 smoothing.
Green shows the OOTB in-room frequency response.
Red shows the OOTB in-room frequency response + bass enhancement activated.
Bass enhancement stays activated for the space tune measurements as well.
Blue shows my first measurement after completing the included space tune calibration. During space tune calibration I did not hold the TV remote (its mic is used for measurements) as intended by the software.
So
Yellow shows my final measurement after completing the built-in automatic space tune again, this time holding the remote as intended. Thought it might be interesting to compare both measurements.
Automatic space tune will create pink noise, adjust the volume level and then proceed to take short sweeps through all built-in speakers.
At this volume level the built-in subwoofer of course distorts like crazy. While skipping through some movies at normal listening levels I heard no distortion, though.

Now for the subjective part: how does the built-in, Dolby Atmos-supporting speaker system sound? The Z95B certainly has the best built-in speakers I have heard on any TV, but I did not spend too much time with it because I strongly prefer my Revel F36s. I did not hear much of a surround- or even Atmos-effect that it is supposed to emulate and did not expect to. Space tune calibration did, however, improve the overall tonality and sound of movies. I watched parts of Heat, All Quiet on the Western Front (2022) and Mad Max Fury Road for testing purposes. The speakers do sound surprisingly full and spacious for a TV set and should be great for casual or late-night watching when not using my stereo or headphones. I have never owned a soundbar, nor a multichannel setup, so cannot compare to either.
Connecting a subwoofer to the Z95Bs sub-out should definitely improve things.
