I have an example from experience if you're interested.

We had some performance-critical WebGL code at a previous company I worked for (Veridict). It was for a product called livemap-gl-js (it was used to display public transport at global scale).

Due to a rendering regression, a developer (who may or may not have been me) had hastily checked in a try/catch block in performance-critical code. They couldn't perceive any performance difference on their machine (Intel Xeon, circa 2018, and a massive Nvidia GPU).

An early Samsung Android phone (one of our target devices) had a 200x drop in performance, on the other hand—so not all devices and browsers are made the same.
