Here's a more generic WebGL texture upload test using a benchmark video that contains solid colors - https://jsfiddle.net/qz9ka6xm

The test uses gl.readPixels to count how many unique colors are rendered and the average upload time. I'm only able to get the 1080p test running on my iOS devices (I believe due to the aspect ratio of the 2160p file going beyond the mobile WebGL texture size limits - I can fix that if so desired), but I'm able to replicate the regression using the 1080p file:

iPadOS 14 GM on iPad Pro ~21fps 
iOS 12.4.8 on iPhone 6 Plus ~24fps
