It counts IMO, because they didn't just bolt on a VR view and call it a day, but reworked gun handling, physical reloading, vehicles, and a ton of other things to make it perfect.
Open-goal for Jak & Daxter probably the most impressive, because they manually decomped an entire trilogy, added a dramatic amount of new features, you can mod in whole new content, and you get solid performance on pretty mild hardware.
Other notables I haven't seen mentioned:
OpenRA - Open-source recreation of Command & Conquer Tiberian Dawn, Red Alert 1 & Dune 2000. A variety of improvements too long to list, they're currently working on Tiberian Sun, and adding in support for the better quality assets from the Remastered collection.
GTA: Vice City: The Next-gen Edition (trailer) - Better than the official "Definitive Edition" remaster, and brings in benefits from the GTAIV engine.
I forget which of the decomps are automating the process, but once we get to the point where a single tech-savvy person can turnaround a decomp with 4k 60fps in a short span of time we'll be in a golden era of game preservation. Also, tools like dgvoodoo, SpecialK, various widescreen fixers, translation layers like Proton, AI upscaling tools for textures, etc have done an already great job at just making it easy to run older games like lite-remasters.
