Non-realtime use cases for UE5 have much more generous performance constraints, and so the giveaways of UE5 are less apparent. Eg. raytracing instead of lumen.
Very few projects change the default diffuse lighting algorithm for raster graphics in UE, which is Lambert shading. It has a particular "look" that reminds me of really early use of graphics shaders in games [0].
