It was working fine for me but now it just shows as Stereo in Windows. Tried different drivers and everything to no avail. Weirdly it works just fine if I try to play the demos on the Dolby Access app but anything outside of that is a dud...

I am one of those. It has always shown up as stereo for me, but I did manage to get Netflix on PC to bitstream Atmos. It requires two HDMI ports, and the Netflix app for Windows 10. You connect one to the speaker, as sound out, and the other to the TV as video out (video from the HDMI on my nvidia gpu, audio out from the Intel motherboard HDMI port).
That way, you also get full RGB 4:4:4 2160p video, instead of the limited 4:2:2 (IIRC) the soundbar passes through, and no Netflix DRM issues either. Both bluray rips and bluray discs pass through Atmos this way as well. Well, as long as you're using MPC HC/LAV filters and turn on bitstreaming.
When browsing Netflix, you can't see which titles are Atmos, but the blue light lights up and you get the Dolby Atmos text scroll and when checking A/V Stats, you get Atmos bitrate 448 kbps (as opposed to 384 kbps for DD 5.1 or 192 kbps for DD+, which also is supported).
Making sure everything is on the right channel is also a bit jank, but it works
