"I’m not sure if there are algorithms that can add high-frequency information that wasn’t captured in the original sampled result"
This is the most important statement , I believe upscaling or upsampling whatever you choose to call it is not more than a voodoo.
You can't add information that is not exist at the original recording it's not more than a manipulation process that might degrade the sound.
