The green used on the website is significantly brighter than on an iPhone. In fact, on the iPhone, I would say the green gives better contrast than the white text on a blue background.
For direct messages, the colored bubbles are only used on messages you send. Messages received are always white text on black background (dark mode) or black text on grey background (light mode).
edit: my bad. "increase contrast" option is on, set years ago.
