As a person with red-green colorblindness, I doubt it. The previous version was fine as had an impossible to miss shape-based indication (the X across the cell).

I wouldn't be surprised if you told me that this was done with colorblind people in mind, I've seen many designers blur the line between accessibility and aspects of their design preferences they tell themselves are about accessibility.

That actually makes sense. There's no reason they couldn't have done a check mark/giant X along with the version number, though.
