At this time, I use a laptop with USB Type-C and a couple of USB Type-A connections (pretty sure my HDMI port is output-only), so I'd need something that supports one of these interfaces... Once Jammy Jellyfish drops, I'll be using Pop!_OS going forwards, though as this is Ubuntu-based, anything that supports Ubuntu should be fine.
I looked at the 'Elgato' products, which look nice and all... But there's (extremely) mixed feedback as to whether they actually work and I've heard that their support pretty much evaporates the second you mention "Linux".
Can anyone recommend a HDMI capture device that either natively supports Linux-based operating systems or can be configured with minimal effort?

If you want cheap stuff and are willing to sacrifice some quality and resolution then i may be able to help you. Just recently i bought myself https://www.amazon.de/gp/product/B08DNBJ7D2/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
It's only 1080p @ 30FPS over USB2 but it works well and image quality is reasonable. You can get this even more cheaply but be careful because there are tons of identical clones, some of which don't even work.
Maybe an issie with broadcast vs. limited color levels?

Well that's kinda the whole point of this thread - what's out there that is actually compatible with Linux-based operating systems... I'm not really familiar with the market at all (the only stuff in this product category which I am familiar with is the 'Elgato' stuff we sell at work, which is apparently not Linux friendly at all), so I thought I'd ask here.
Price is not really a concern for me...
By "Epiphan"? You weren't kidding about the price, though they do like awfully nice (both cosmetically and in terms of specifications)...

Also: https://obsproject.com/forum/resources/full-vs-partial-color-ranges-explained-for-streaming.1029/
If it didn't completely crushed lower or upper ends, you can try to change the color levels.
Does the following:
mpv /path/to/the/stream.ext --vf=format=colorlevels=full
or this:
mpv /path/to/the/stream.ext --vf=format=colorlevels=limited
Correct the issue?
If the answer is yes, then you may be able to change the color range before capturing.
