In regards to video, we're probably stuck in cloud streaming land with all the magical (and ever more invasive as time passes) DRM, sadly. Audio? Not so much (unless you count MQA as a DRM of sorts, which I do). I remember Apple started out adding DRM to their music downloads a decade ago, but eventually they stopped doing that and went DRM-free. I haven't seen any DRM on music downloads in a long, long time. Video? That's a different beast altogether due to all the piracy and DRM, especially on physical media (which hasn't happened to music CDs in a decade). I would be *highly* surprised if a legit store started with DRM-free video downloads of mainstream films and TV shows. But... there are sites, like Vimeo, where you can get DRM-free downloads of video content from the creators themselves, e.g. it's good for some documentaries and stuff like that. Overall though, I just don't see that happening for mainstream films and TV shows. So no, I don't think it'll happen to video like it has for audio.
Unless, of course, you're one of those types who purchases physical media (e.g. DVDs, Blu-rays and/or UHD Blu-rays) and rip those and put them on a NAS or something like that. Which, looking at your post above, doesn't seem to me like you are.
