Are there any neural nets trained to calculate the native resolution of a render, pre upscale?

I’m asking specifically because YouTube channels like Digital Foundry are getting stressed out and spending an inordinate amount of time finding the range for dynamic resolutions for modern games, and I was wondering if there were any tools that could be utilized to automate the process.

It would be a great shame if anyone on their team quit due to the stress and tedium that has resulted from dynamic resolution scaling, as they provide invaluable technical information in the field of real time rendering.
