It may be a bug in the rounding/truncation of signed hex. numbers to decimals—e.g. moving the slider from +1 to 0 actually gives +0.01 / 0x00000001 which is then truncated and stored as 0x0000, which then reads 0 after; whereas moving the slider to -1 to 0 gives -0.01 / 0xFFFFFFFFE which is then truncated and stored as 0xFFFF, which then reads -1 after.
So is it actually at 0 now or is it telling me it's 0, but it's actually 1 over to the right?
And what about the volume slider? by default, the PEQ filters are at -5dB, but the volume slider on the right there is at -/+0 -- is it safe to raise the volume slider up 4 or 5dB or is it best to leave it where it is?
I can confirm that they're selling the OG black pearl again, at least from the official store from the local marketplace in my region. I had to ask 2 times for confirmation just in case they're selling the new ones but apparently they're only selling the old version now since I didn't see any complaints in the reviews. YMMV of course so just double check with the seller.
Also it came with version 0.6. Not sure what changed though.

I do recall reading that NOS mode does internally disable DRE. But is there no way to disable DRE whilst still having a proper reconstruction filter active? (This is exactly how I have set my Fiio Melody).

Correct. I also have the Snowsky Melody and I also hear slight distortion unless I toggle the DRE Disable. I don't like using NOS as I don't oversample.

Yes it does. But not-oversampling isn't a good idea, so instead you can use NOS mode on the DAC and have your OS/music-player oversample.
To quote the first post on this thread:
When a DAC is set to 'NOS', the signal is supposed to be converted to analog audio without this reconstruction filtering. The consequence is broken soundwaves, shown in measurements as an early high-frequency roll-off and severe ultrasonic distortion. For this reason, when the NOS mode is used, the input signal should be oversampled by the host system.
As a follow-up: I checked the online walk play app, and I believe that the 0.5 / 0.6 distinction is probably hardware revisions? When I checked for FW updates, it said mine was on the latest version.

I checked mine and compared the look of the PCB (at least the one visible on the glass) and it looks the same as the one on the first page so there might be some slight changes inside? Here's what it looks like in the app though I have no idea what the Chinese characters mean.

On the web app (there is no iOS app, so that's what I have to use), there's a button to the left of the "Connect/Disconnect" button that says (when popped into Google translate) FW Update. Clicking on that, brings up a dialogue box with a purple button to check for FW updates (again, that's what it says when popped into Google translate), and the results say that my BP (v0.5) is on the latest update (again according to Google translate).
I do not know if there's any difference between what mine is running on (or really any way to check what FW version it's on if the 0.5/0.6 is a HW revision value), but I can post some screenshots of what options are available to me in the web app.
