Most everything i read is that it needs 1440p/50/60fps to really make a difference and  impressions are all over the place, with many saying it useless and others say it's great. many saying it make the image worse and the input lag sucks.

DLSS 3.0 is an entirely different beast from DLSS 2.0. DLSS 2.0 improves image quality beyond the internal render resolution regardless of that render resolution and even is better than native target resolution in numerous cases. Even FSR does this, which is why there are countless videos of how best to use FSR with the Steam Deck (native resolution of 1280 x 800) to improve battery life with minimal image-quality loss (if any.) 

DLSS 3.0, because the goal is temporal interpolation (producing missing frames, and not just missing pixels) has a few quirks that will have to be worked out. But the Switch 2 likely won't even support DLSS 3.0 anyway. Ampere's Optical Flow Accelerator (OFA) isn't fast enough. That's why the 3000 series Nvidia GPU's don't have DLSS 3.0 (or at least according to Nvidia that is why, which seemed suspect until they announced 3.5 for all RTX GPU's.) 

One of the things that has hindered the original Switch is that games have to work well in both portable and docked mode, and in portable mode you can't have a battery life of 30 minutes because the game is pushing the platform to its limits. DLSS 2.0 allows for far more flexibility in this sphere, even for Nintendo themselves. You'll rarely have situations where resolution falls to 360p (i.e Xenoblade 2), for example, like we've seen on the Switch. 

My guess is that the internal resolution will always be between 720p - 1080p, and the effective resolution (after applying DLSS) will be between 1080p and 1440p when docked, with many games targeting 60fps that wouldn't otherwise have. If Nintendo were savvy, they'd put a VRR screen in the device, and many games could even target stable 40fps or 50fps without much screen-tearing. 

While PS5 level visuals/framerates is indeed hyperbolic, being able to meet or even exceed the Series S in many cases (or at least there will be trade-offs where there is no clear better version) is certainly doable. That is all the Switch 2 needs to do to keep up with the current generation.
