IIUC Chinese manufacturers often put the "CE" mark on things that haven't been certified, and rationalize it as the mark meaning "China Export"
I have never heard of a case of a homeowner's insurance claim being denied based on imrpoper DIY work. One of the main points of insurance is to protect you against your own negligence.
Still, I would make the same decision and steer clear of such lighting fixtures!
CE conformity is a self-declaration by the manufacturer, so essentially the honor system, not an actual certification program like TüV. Items without a CE mark cannot legally be imported or sold in the EU, but there is little enforcement.
CSA and UL are definitely 3rd party assessments though.
Ah yes, I'd looked this up before but then forgotten it. My original comment would be better stated as "Chinese manufacturers often put the 'CE' mark on things they haven't designed to conform to the guidelines, and have no intention of standing behind the liability for ..."
The replacement ones that the electrician selected were only slightly more expensive and I was able to clean up the look of them with 3d printed shrouds:

I've really got to get back into 3D printing. I was building a Voron back when it would have been like serial number 20. Got it to the point where I was printing its own parts (using stub parts made of plywood and whatnot). Life happened, I disassembled it to move, and I've still got the frame sitting around plastic-wrapped for the past ten years.
I wasn't even thinking LED fixtures. For LED fixtures with built in power electronics, I would definitely want the product to be NRTL recognized.
I was late to the 3d printing game and in part that was just not wanting it to become a junk factory of disposable toys and fidgets. I've definitely printed a bit of that kind of thing but overall I've been pleased with the number of small household fixups that it's been possible to do using it.
Just last night for example my microwave oven stopped registering that the door was closed, and within a few tries I was able to print a replacement for the latch bracket that had broken off. At any previous time in my life that would have been either a whole new door or replacing the entire unit.
