Yeah, I'm not sure if the physical Cash Magnet cards have been adjusted, but it appears that all the card art otherwise has been lightened - in the app/on the web site someone replaced it with a low-resolution, pixelated version; in Apple Pay, it changed overnight last week. Personally, I'm not a fan just because it's a bit jarring and the plastic card looked really nice, but I get the desire to have slightly different looks among cards in the same family.
