Obviously the two screens are going to produce a slightly different hue. But manufacturers try to get that as close to "true" as possible.
This is how you can tell what elements the sun and other stars are made up. The light frequency stays constant - doesn't matter if you view it from space or filtered through the earth's atmosphere. The only way it would change is if you were moving really fast. In fact astronomers use this red shift, knowing spectral signatures of common elements of the stars - to tell how fast they're moving away from us.
Also how many times do you see a bright blue screen like that one a phone - especially where most of it is empty space - on any app or homescreen?
There are lots of factors here. First, every display device will have a different color calibration. Second, there's the color response of the Stone's cameras that captured the video, then the gamma conversion that encoded that video, then the compression applied, then the possible recompression at YT/Twitch. Lots and lots of color transformations. If they needed to a color technician could profile all the displays involved and come up with a set of LUTs to definitively map one color to another to prove whether or not the screen on Mike's phone matches the server. But it'll probably be much easier to just do a forensic check of all the devices and network logs instead to prove that out.
