Yes.
I think this is where we need to look past what we expected and what we knew was happening, and think about what most viewers would have expected, and I think that what most people were expecting was probably something along the lines of the PS4 reveal - some hardware talk, some games, and maybe some additional information about peripherals and such.
Instead they got an hour-long talk about bandwidths of storage devices, BVH, and 3D audio. They might care about what effects those things have on games, graphics and sound, but they won't have cared enough to want to hear someone talk about them extensively.
This kind of talk would have been fine as, say, the fourth video Sony released about the PS5 (if labelled and communicated properly), but not as the first substantial video about the system.
