Does anyone know why HDR looks better on Linux than Windows?

So I'm debating about try linux again (accidently deleted my audio drivers among other things and then reinstalling windows was a hassle itself. Don't ask, I'm stupid, I'm well aware) I have ubunto installed on a separate hard drive right now and I started playing poe and I remembered how much better it looked on Linux but I'm not sure why and I was wondering if anyone could tell me and if there's a way to make the windows HDR better
