For most of these small sensors you'll need to crack open the device to find out exactly what hardware is really there. More than once I bought at different times apparently identical Zigbee sensors which behaved very differently and it turned out they were different inside despite having the same model name. Probably a hardware revision thing but with no clear markings. Manufacturer couldn't find some component anymore or not for a good price and instead redesigned the device.
Those who care about the internals are techies who maybe want to build their own or are very curious. Most buyers don't care about that, they care about how well it works in practice. Just like they don't care what RAM chips are used in their phone or computer, what modem, what screen panel, what camera sensor, etc.
If they change components the properties in this test would also change so not sure I get your point other than that any test is useless since manufacturers change stuff without telling the buyers pr changing model numbers.
Unfortunately a lot of these tests are useless because the manufacturers often change the insides without warning. It’s better when they mark different hardware revisions but still not great because reviews rarely get an update.
I have a bucket of devices which don’t do what I hoped they’d do because they were different from what the reviews said. And not just IoT unfortunately. Some do a better job at flagging these changes, some don’t.
But in the end taking the common case that the product is what it says on the box or that the changes have no impact on how it works, most people don’t care about the name of the chips. Not unless they are very keen on the tech and then there are more tech-oriented niche sites that might provide this.
But name of chip would be a decent way for people to get a rough idea for if the manufacturer have change it so to me that seems like a useful piece of data.
