^This. 10-15 years ago, people who wanted an inexpensive theater-like surround sound were picking up home-theater-in-a-box setups for ~$200; some even combined the DVD player. I talked a couple of girlfriends at the time into getting one (if they ever wanted me to come to their home for "movie night" ). Now retailers are pushing the sound bars as add-ons to new TV purchases. Even my dad, who was an earlier adopter for home theater audio, switched to a sound platform two years ago to eliminate the clutter of his 5.1 surround system (which is now my bedroom system). There definitely isn't as much incentive now for streaming platforms to stay current on the audio side, as the push for more 4K content has probably taken priority.
I must be weird. I think my 5.2.2 "true" Atmos pairs nicely with my 65" OLED 4k HDR10 or DV. I started this post and now that I have watched HM2 I'll be leaving Hulu again after my latest free month is up. I just refuse to watch programs with stereo.
