I think you have missed the point of those images/spreadsheet.... That's the whole point of this, to show how many amd sponsored titles didn't get dlss until HUB and gamernexus questioned AMD and then suddently, amd sponsored games started to get dlss added.
Also, amds chief gaming engineer has even made many comments before about not wanting developers to support dlss because of its "closed source nature" etc. he said this in the DF interview with Alex, same way he didn't want to support nvidias "open source" streamline solution.
And another one, remember that space shooter called boundary, was nvidia sponsored, had reflex, dlss and RT implemented and shown in previews, amd got involved as the new sponsor and low and behold, all of that got removed....
Even though Surgical Scalpels showcased some really GPU-heavy RT effects for Boundary, the game will not feature any of them at launch.
