Look. Selecting colors based on a color wheel is an incredibly weak algorithm. For starters, we have not even agreed yet what the color wheel should look like. And obviously, you can not select a color with mathematical accuracy if you don't even agree with the underlying construct you use to select things.
See, the color wheel and color theory are Humanist constructs, not a scientific one (like hard sciences). This is why we have color theory and color science as separate subjects. Now, color science cannot help us here because there is no clear evidence that a color wheel makes sense as an interpretation other than: If you have 3 things to mix, yeah, it's someway cyclic in a plane. Which can have an interpretation of a wheel if you particularly want to have a nice simple shape*. If we would have 2, then it would be a line; if we would have 4, then it would be something more complex.
So the wheel is primarily a tool to help you think. Not so much of an exact tool.
Image 1: See, the color is close to 120 degrees, marked by lines. Wheel by color.adobe.com
Note: color.adobe.com uses some derivative of LCh color wheel. So, being harmonious according to theory just depends on the wheel used. Note it can be that the image is 120 degrees but has a blue filter on top of it... Since human senses are relative, that's fine that gets filtered away. Maybe the unconscious idea is to make the white warmer? Or perhaps authors monitor was calibrated clearly yellow. Who knows.
* If color science would try to build this, it would probably be a color blob. But they don't so... and the wheel is much nicer than blob.
