Change scaling algorithm for non-retina apps running in low resolution on a retina display?

Regarding non-retina apps running in low-resolution mode on a retina display: - In the past, circa 2012 (ref ), these apps were scaled with nearest-neightbour algorithm, where 1 pixel would become a group of 4 identical pixels. Confirmed in Apple Docs from the period - At some point since then, at least by 2016 (ref ), these apps are now scaled with a bilinear (or similar) filter meaning that a single pixel does not get scaled up cleanly and the resulting group of 4 pixels is blurred with surrounding pixels So, my question: is there a way to change the scaling algorithm back to nearest-neighbour?
