1440p is not a TV resolution. Games could run at 1440p120 and upscale to 4K with FSR if they want to.
Yeah, Sony has a history of only supporting TV standards on PlayStation compared to Microsoft's approach on Xbox.
My issue is when the display it self is 1440p. Then you are stuck with downscaling 4k 60 fps (because 4k 120 is too much for PS as well as required HDMI 2.1) or upscaling 1080p 120fps which doesn't look that great.
