Only in cases where NV determines it is in their best interest to train it for DLSS. IE - only for the biggest titles or for titles that NV think will get benchmarked on a review site. And once the game is out of the limelight it's unlikely it'll get any further training. So a game with a lot of pre-launch hype will get training, but if sales for the game are disappointing, I can see further training coming to an abrupt end.
Otherwise, you're SOL.

Isn't DLSS a way for Nvidia to lock customers to their GPUs like Gsync is ? Well at least Gsync is working as intended.
