That would certainly make certification easier, but as I suspect you understand, wouldnt achieve it alone.
Even if every component was CE qualified, the combination would have to pass its own testing, plus there are a lot more to the standards than just not electrocuting you immediately upon contact.
I can't see any of the energy efficiency labelling that would be required in the UK or EU for example...
I'm curious that this story seems to be missing a big part of hardware design - certification.
It seems like the design was being changed up to the minute these were shipped to customers, so it doesn't seem possible that any testing was carried out on the final design?
The live prongs are insulated to such a length you should not be able to touch any conductive part before the plug is no longer making electrical contact with the socket.
It's likely you got a small zap from a filtering capacitor inside the device that had not yet discharged.
It's possible that buying the TV and removing the toxisity is more effective - you get the subsidised price, but the manufacturer never makes the ad money back.
I run Blueiris (https://blueirissoftware.com/). The beauty is you can run a mix of cameras, so I have decent Hikvision ones outside and whatever cheap PTZ I find at a good price inside.
Multiple sources spread over an area would be more efficient, as each LED could run at lower current and temperature, which increases their efficacy.
The light would also not have to bounce off ceilings/walls multiple times, while some are nice for diffusion, every reflection is lossy.
I suspect you’d also get better reliability.
