I mean, this is c/piracy, you can pretty easily go download a non-HDR version of everything. If you do want HDR just not DV, most decent DV encodes also have a HDR10 fallback which should kick in if your device doesn't support DV.
Alternatively, I'm pretty sure there are plenty of tools out there like DoVi Tool that can help you convert the HDR metadata to HDR10/10+ if that's what you want.
Dolby Atmos is able to be played on a wide range of modern device. Android-based phones can do it. Cheaper TVs can, and cheap soundbars give a satisfying experience. You can listen to Atmos content on headphones
