I had to post this because I love Hellblade: Senua's Sacrifice on PC, still one of my favorite Indie game so far. As for how the Switch stack up compare to PS4:
- Too much Blur on Switch.
- Lower Resolution compare to PS4.
- More pop-in during rendering.
- Washed out lighting & no character shadows on Switch.
- The framerate is reasonably solid for a much weaker hardware so that's saying something
Overall, yes it's obviously downgraded in every relevant category, from model details to shaders to lighting to textures. But it's still recognizable and looks good for the Switch system on it's own. Hellblade is still one of the best Walking Simulator game (not cinematic so let's get that out of the way) I personally enjoy and should be played using headphones.
