Those are all good questions @hell001

Is this a reversible process? As in if I had the hybrid file, could I revert back to HDR-only and DV-only files? Or would I have need to kept the separated files if I wanted them split again? If it's possible, could someone provide some script examples?
You can get back the HDR10-only file from the hybrid, but not the DV-only file. The reason for that is a P8 hybrid takes everything from the HDR10 file and then adds only part of the DV file. The part that's added is called the RPU, and is the precious DV metadata, and so we extract that out, and then discard the rest of the video information from the DV-only source file.

There are many different TVs and streaming clients. From what I understand, some of them either do or don't support Profile 5. Or Profile 7. Or Profile 8. If I was using a client that does not support Profile 8, wouldn't I be out of luck with the hybrid file even though it has DV? Whereas I could have actually been watching in DV if I had just used the DV-only Profile 5 file? So it's not like creating these hybrid files is the one-size-fits-all solution and it is NOT safe to assume that after this process we will always be watching in DV, right?
Yes, that's right. For me, the point of making hybrids is that it gives the highest possible quality for movies that are available on UHDBD, but don't have DV on the disc. So we extract the DV from the WEB-DL, add that to the HDR10 from the disc, and have the best of both worlds with the high-bitrate video from the disc and the DV metadata from the download to allow your TV to do the best-possible tonemapping.
I hadn't actually heard before of people making hybrids where both the HDR10 and the DV come from different WEB-DL rips. I guess the point of that is if you have a device that can do P8, but not P5? To be honest, in that scenario I would strongly advise just getting another device that can do P5 if at all possible, because they're easy to find and cheap, and making hybrids is always time-consuming even if you have scripts to help.

Related to the above, I am interested in hearing some of your setups that take advantage of this hybrid process where the comments in my previous question are not an issue. What do you do in scenarios where it doesn't play in DV?
@RESET_9999 made a
fantastic spreadsheet summarizing the playback device options with their pros and cons, but my personal setup that I'm very very happy with is:
- Sony X800M2 for P7 rips (where the original disc had DV), P8 hybrid rips (where the original disc didn't have DV), and HDR10 rips (where I haven't been able to find a DV source)
- Apple TV 4K for P5 rips and all streaming
The only substantial compromises with the X800M2 are that you have to use M2TS files (easy when you know how), you don't get chapters, have to manually turn on any forced subtitles, and have to use Wi-Fi rather than Ethernet because it only has a 100Mbps Ethernet port which isn't fast enough. But those are all well worth it imo for the best-possible-available video and audio quality.
You can swap the Apple TV 4K for something else if you don't like Apple or disapprove of the price, but since P5 is the totally mainstream format used for DV streaming it's well-supported by lots of devices.
