Here’s a quick test of an older splash screen scene cropped in on the face, with spectral, then spectral with a custom importance spectrum, then RGB. There’s something odd going on in the left eyeball but that might potentially just be a result of un-resolved values being initially somewhat biased. The spectrum sampling improvement is noticeable but not all that significant, which is about what I’d expect with this scene.
It’s interesting just how different they are to the RGB scene. I’m looking forward to when we have a spectral version of filmic ready to use because I feel that will hugely improve the visual appeal of the output images by default.
