Surprised you didn't know this. This has been UL's requirement for decades for TV mounts.
To be clear however, that 4x rating is for it outright breaking (snapping). The mount will for sure be bending at less than 1/2 that. How and what the mount is anchored to will also determine how much it can take.
But the rating the mount advertises should be solid. Although I remember some people complaining about how much sag the SnapAV mounts had years ago. Not sure if they have improved upon that or not. Seems important however considering the tight tolerances you seem to have on this particular install.
To get the UL Listing, a mount rated at 100 lbs must hold 400 lbs without Bending.
The Standard requires a mount to be tested to at least four times its weight rating (if supporting a TV weighing 100 pounds or less), or two times its weight rating plus 200 pounds (if supporting a TV heavier than 100 pounds). The TV mounts must be able to resist cracking, bending or distortion to pass the test.
