It was just revealed yesterday that Nintendo filed a patent in March 2020 titled 'systems and methods for machine learned image conversion'. Basically, an internal technology similar to Nvidia's DLSS used to upscale to higher resolutions using machine learning. That could be 4K if it's tied in with a new model to be released in the future. That would also explain why they directly addressed rumours of a Switch Pro amidst the launch of the OLED model. Wouldn't want to hurt sales of your new model if you have a better one around the corner..
