I doubt it, but it would be interesting if they recorded Stadia sessions and trained on that data (... somehow removing the hud?), seems like it would be the easiest way for them to get the data for this.
Seems somewhat likely to me. They probably even trained a model to do both frame generation and upscaling to allow the hardware to work more efficiently while being able to predict the future based on user input (to reduce perceived latency). Seems like Genie is just that but extrapolated much further.
