Does the whole "Lock Screen is just UI" thing also hold true on Samsung phones where they use Knox? Samsung phones seem to have a long delay after the PIN is entered in for the first time.

By "Entered for the first time", I assume you mean after a fresh boot? If so, that means the phone is Before First Unlock (BFU), where the user data is actually encrypted. The "Lock Screen is just a UI" applies to After First Unlock where its just a UI element. BFU and AFU are essentially the core two states in the mobile device security world. Not sure why it would take a long time on Samsung devices though, it's usually almost instant on most handsets.

One would think agencies like the NSA, whose mission is nominally to improve the communications security of Americans, would be helping Apple and Google with patching the 0days that foreign companies like Cellebrite are hoarding.
Instead it seems like everyone is teaming up to fuck over the average person. What a great world we live in.
