The framing is fair unless you expect NVIDIA to ditch their ML based solution for a class of inferior implementations which in turn can run just about anywhere.

The framing is fair unless you expect NVIDIA to ditch their ML based solution for a class of inferior implementations which in turn can run just about anywhere. DLSS isn't "NVIDIA flavored FSR", it's a more advanced pipeline that requires significantly more architectural alignment. FSR 3 was going to be the closest thing to an equivalent and won't run everywhere FSR 2 does.
