What form of color blindness doesn't let people differentiate between levels of brightness? I checked a couple color blindness simulators and it appears legible.
Heck, white on light green appears to be used in articles about good design for color blind accessibility without any indication that it there's anything wrong with it.
As someone with strong deuteranopia (I struggle to differentiate shades of green and darker bluey-reds), I am extremely sceptical about that claim too. For what it's worth, I've never had a problem reading the white-on-green bubbles in Messages. I do agree that a contrast closer to WCAG's recommendation would be better (currently 2:1, recommendation is ~4.5:1), but this is a diversion. The point I was making is that no matter what Apple does here, there is visible differentiation, and people will complain about it.
