I don’t think you’d even get that, as it’s not really relevant to what they are doing or meant to do, even the game engineers. And in Nintendo’s case they’d prefer to give you the software details. The only way one would know is if they open up the device, look at the silicon in the device and see if it mentions anything about Samsung or TSMC.
However, there’s issues with doing so:
1) requires you to open it up, and you can tell if someone opened up a developer kit.
2) stemming from 1, these can be easily traced back, as a dev kit can be assigned to you that Nintendo would know which developer kit is or was under your care and not remotely visa some technology but a simple method. Company Alpha requested a developer kit, they receive kit that has the numbers 123456789. Developer kit is returned and has been tampered with, is investigated, who had kit 123456789? Oh it was company alpha. And then more investigation. Was it dropped? No it was not… then it was opened, for what purpose? Etc.
3) stemming from the second, you put not only yourself at risk, but you put your colleagues and your company at risk of being blacklisted.
So, you wouldn’t find this stuff out until it’s told via Nvidia or by Nintendo if they ever do that. Another way is that they don’t tell you and a few weeks after the launch of the console, you get someone opening it up. Takes a pic. Posts it online.
The most Nintendo would tell them is that it is a custom NVIDIA Tegra Processor (because that is what it is)
