An interesting aside to this conversation is that although MS don't appear to have changed how the digital license is stored on their servers, they do seem to have recently taken steps to retain the OEM or Retail status on the PC itself.
My System One below got the free upgrade to W10 in August 2015, and in the process it's OEM install of Win7 became indistinguishable from a Retail install of W10 Home, with the generic retail W10 key and a retail product ID, as shown by ShowKeyPlus.

As an experiment I recently restored it's W7 image, then did an in-place upgrade to the current W10 20H2. This time round it got an OEM product ID, and the Toshiba generic OEM SLP W7 key was replaced with the generic Windows 10 Home 'Default Product Key to be used with OEM Activation 3.0 - for manufacturers'.
