Why would it matter?
Because if you have laptops with Nvidia Optimus, distros like pop_os make your life much easier since nvidia doesn't give two shits about Optimus on linux, hence the famous "nvidia, f*ck you!" quote from Linus Torvalds. Or if you have a brand new laptop with the latest Ryzen CPUs and the latest Radeon 6800M GPU with switchable graphics then you absolutely need a distro with the latest kernel to have a good experience…
So I asked why it matters if its 'pop_OS' or not since if that happens to bundle some driver, or Steam, or whatever, I assume I can continue not using 'pop_OS' and still install whatever it is if I want?
It just seems like an irrelevant detail, (and potentially not even a valid one? the more you do subsequently the less it 'is' that distro) outside of saying 'everything worked out of the box, didn't have to install a thing', which may or may not have been true, but wasn't what was claimed.
