That was just my personal preference, you can easily generate it with a white background too. Actually, you can even make it with a transparent background, but it's possible that it will mess up some minor things (and those tend to get more noticeable with a transparent background, like missing pieces in the veil between the hair strands).

One thing to keep in mind is that ChatGPT/Sora/Copilot (they all use the same model) usually generate stuff with too reddish tones (grayscale pictures are an exception), I personally try to fix that in Photoshop using levels (0.9 red, 1.2 blue).
