“Caught in 4K” is like saying someone got caught doing something wrong on camera. It means there’s clear and detailed evidence, often in high-quality video. So, if someone is caught cheating or breaking a rule, people might say, “They were caught in 4K,” meaning the proof is so clear that it’s impossible to deny what happened.

It’s a way of emphasizing how precise and detailed the evidence is when someone is recorded doing something they shouldn’t be doing, making it hard for them to say it didn’t happen.

Example

“That woman in the supermarket was caught in 4k. We watched the entire footage, and it was so obvious.”
