Correct! All icons are actually different.. As you know, LMS, contrite's icon is missing on Chromebook devices. Additionally; the icons for a majority of the red relics are much smaller on Android devices. The circles that are a part of the green relics are also way larger on those devices.
But yeah, that's just how the fonts are made. It's quite fun however to discover these differences across different devices! What do you think? :)
