Sounds like you're moving the goalposts from "haha CBP agents are dumb" to "they should get warrants".
1. They do field tests before sending to a lab
2. They're sending it to a lab to ensure the results are accurate, not to guard against an off chance something is boobytrapped.
A duress password isn't a booby trap. Nothing was damaged except for the fragile egos of the man-children who weren't able to bully someone into giving up their wrong-think.

The conviction was overturned, but only on procedural grounds
But, let’s say somebody unknowingly has evidence to a case, then in the time it takes for law enforcement to retrieve it, accidentally or otherwise destroys it, but necessarily not knowing that it was any sort of evidence. Would a case hold up in that situation if law decides to pin it on the person in question? Personally, I think situationally, it should not, but I don’t know how much faith I have that that would be the case.
Anyways, pertaining to the topic - in the same spirit of case-by-case, I’m not surprised by the outcome even if I’m glad the functionality worked here.
"Give us the PIN for your phone"
"I don't want you to search my phone, and I want to talk to my lawyer"
"If you don't comply, you're going to be in a lot of trouble"
"Can I please just go, I don't want to answer questions or be searched"
"If you don't comply we will seize your phone and detain you indefinitely until we can unlock your phone!"
"I want my lawyer."
"Just tell us the PIN and you'll be on your way. Otherwise it's gonna be bad."
"Look if I have no choice my PIN is 1234, but I don't want you searching my phone without my lawyer present."
...
"Hey! We tried to search your phone and the phone wiped itself! You're going to prison for destruction of evidence!"
