Assuming this is a serious question about why the rounded square is even there to begin with…
Spectral colours are beyond the sRGB gamut. They cannot be encoded by the colour space of that image and could certainly never be properly displayed by your screen. I won’t get into the maths here, not that it’s particularly involved, but it is easily doable to represent the colour of spectral light shining against a grey background within the sRGB gamut.
Although I made the purple circle dominate far too much of it for the proper effect to appear, I think.
This is one the most accurate renderings of the visible spectrum you’ll find on the internet. Most others distort the colours, have huge uniform bands where they shouldn’t be, etc.
Then the rounded corners are just to be more artsy or something.
Somebody made an update and I clearly blanked on this reply from almost 6 months ago, of which I've understood maybe some of the words.
TBH my reply was just a shitpost implying I couldn't see purple based on the principle that it doesn't exist.
I think you're saying that the colour-spaces don't translate into each other well, one being a single dimension, and the other being entirely contained to a cube. I wouldn't want to get into the maths of that either, but then maybe it's simpler than I thought and something else is the complicated part.
I'm always up for some artsy rounded corners ofc.
Fun fact: HSB is two cones glued together with a grey-tasting center.
