What is this Non-conforming green on button on my iPhone 6+?

Non-conforming green "on" button--iphone 6+

When I touch one of the on-off buttons, and it turns green (for on)...I have a small vertical white line in the left portion of the green. Everyone I've met, with the iphone 6+, has a SOLID green "on" button. Is the little solid white line a cause for concern?
Thanks,
Don

It's an accessibility setting... Settings>> General>> Accessibility>> On/Off Labels
