"mostly", but there are notable examples. Intelligent Systems Fire Emblem Engage, Atlus' Shin Megami Tensei 3 HD port, or Bethesda Classic Doom re-release come to mind for bigger company Unity releases. It is less prominent in AAA, but not every company can afford to build their own RE Engine, and some companies chose Unity over Unreal, which in hindsight is stupid. Or might be related to them working on the Wii U before, where Unity was officially supported (you even got a free license as a Wii U developer), while Unreal Engine 4 wasn't supported (until it was?). Maybe not a big deal given that there's like ten Wii U games in total, and that Unreal is supported on the Switch (Yoshi's Crafted World and Octopath Traveler come to mind).
