recently my android phone (Nokia 7.1) has been showing all videos as inverted colours. This includes videos in YouTube, Snapchat, my camera roll, etc. However the previews/thumbnails show the correct colours still. The OS itself, when browsing chrome, emails, swiping the home screen, etc shows the colours correctly. Restarting my phone temporarily fixes the issue. Any ideas as to what could be happening? Settings > accessibility > colour inversion is not turned on.
