Part of the fun of emulators is you can make games look the way they really should.
It's been a staple of the Dolphin emulator for Gamecube and Wii games, and its a feature that is being included in the latest update to the cemu Wii U emulator. The latest version, 1.7.0, is currently only available to Patreon supporters, but it'll be released to the public in about a week.
Until then, here's a taste of just how pretty Wii U games can be.

The 4K graphic packs, which lets you configure anti-aliasing, resolution, shadow quality, post-processing, level of lighting effects and more, are only available for a handful of games right now. The video below runs through a side-by-side analysis of some of the games available. (The video is best viewed at 4K, but even at regular 1080p you can see the improved textures, anti-aliasing and overall better image quality.)
If you'd like to view some of the screenshots in their original quality - or at least untarnished by YouTube's video processing - there's a great NeoGAF thread with plenty.
