Yes, the difference between hair in video game lighting and in actual chiaroscuro with the way light really works is going to be different.
Here’s a painting from over a hundred years ago. The subject doesn’t have brown roots, but is in shadow. And a comparison image of the exact same hair in different lighting conditions.
Performing complex lighting on individual hair strands is really expensive so in the base image you have a kind of diffuse lighting throughout the hair. With the DLSS 5 on, the distribution of light throughout the hair is variable leading to darker unlit strands underneath lit surface strands.
Literally the only thing DLSS 5 is changing, literally in the technical sense, is the lighting. It’s just that lighting can have dramatic results in how the eye perceives what’s lit.
And yes, the hair looks very different, but that’s how hair actually looks in mixed light and shadow (though a fair complaint with DLSS 5 is that it looks like it’s sliding the contrast unnaturally high).

That painting doesn’t look anything the same, and nor do those pictures. In the bride she’s a natural blonde. In the after she’s a bleach blonde
