it exist, just not (yet?) in Europe ...
4KVC00, interesting model worth to have a closer look at. And it
seemingly is available or at least prices in Europe for €71.99

If it has better cost/performance than other similar UVC v4L2 models, I
don't know.
Looking at its tech specs, it has color precision
Deep Color 4K@60Hz: Up to 8bit
Not really fair comparable with the "not so unexpensive" standalone SSD
recorder (BMD Hyperdeck Shuttle 2

A true YUY2, USB 3.0 capture card capable of 1080p 60fps!
Reviewed in the United States on June 7, 2021
For the price, this thing is awesome. It's actually USB 3.0
(instead of just a fake blue connector) and is capable of
delivering raw 1080p60 video for capture! I've been looking around
for a good 1080p60 capture card for my Nintendo Switch, and this
fits the bill quite nicely, as the loop-out keeps the gaming
'competitive' while the capture looks great.
Pros:
- Really captures at 1080p 60fps, and delivers sharp images
(instead of blurrier 30fps ones you'll find on cheap USB 2.0
MJPEG-based capture cards). YUY2 (the video format) is chroma
subsampled though, which means that really small text may have a
bit of discoloration, but for games it's not really an issue.
- Low latency capture (at least from what I can tell in OBS preview)
- Loop out (yay)
- Works with Linux as a simple V4L2 capture device
- Sound is nicely in sync
- Price (I got it for like ~$40 or so, and haven't found anything
this good at this price point - heck, it outclasses my AverMedia
Live Gamer Mini I bought used at $60)

aja and other stuff cost ... *much* more.
https://www.aja.com/products/u-tap-hdmi
439$
https://www.amx.com/en/products/uvc1-4k
even costlier, 800+!
Anyway, in all cases cable (usb) might be limiting factor, too?
I really hope this HAMA device actually just was plugged in wrong
port or via wrong cable, otherwise I think it will be wise to
replace it with something else (sadly cheap-end devices may change
their guts without changing appearance, so ...russian roulette!)
