Hi…which Nexus device are you referring to? Off the top of my head Nexus 9 has a buffer size of 128, Nexus 6P has 192 and Nexus 5X has 192.
Incidentally I think you mean 96 frames on Pixel, not 94.
Either way, 1920 is a very large buffer and unless it’s a very old Nexus device it sounds too high to be correct.
