Yes, duh. It's a console, resolution scaling is the #1 foremost tool in their arsenal for stabilizing the framerate. I can't think of a console game made in the past decade that doesn't "fake frames" at some part of the pipeline.

I'll also go a step further - not every machine-learning pass is frame generation. Nvidia uses AI for DLAA, a form of DLSS that works with 100% input resolution as a denoiser/antialiasing combined pass. It's absolutely excellent if your GPU can keep up with the displayed content.
