I've heard of exhaust testing but never testing the lights.
Yeah, LED are easy to pick out once you know what you are looking for but other than asking to see a sticker or sales receipt that says they are DOT approved, I really doubt the average inspector could pick out the color wavelength pattern without some expensive tools. I guess it could happen but not something I would be overly concerned with.
I'm very familiar with the LED light patterns having gone thru testing and updated specs for LED traffic signals. It's really easy to put out a red LED that will absolutely blind you and still use negligible wattage.

Honestly, I'm shocked that no one has caught on to the biggest advantage to LED Brake Lights and made them standard on all new vehicles. When you apply power to an incandescent bulb, it actually takes about 0.5 seconds to heat up enough to generate visible light. LED bulbs usually are under 0.05 seconds. That means the guy behind you gets almost an extra 1/2 second to react when you hit the brakes.
The result is near misses become non-events and serious crashes may become fender benders.
I remember reading an article when LED's first started to become popular and the article stated that while driving 60 mph, the difference in time it takes for a traditional incandescant light to light up versus an LED equivalent equates to 15 feet traveled. Thats quite an improvement is stopping distance in my opinion.

Ran into this alot back in my off-road trucking and Jeep days... You purchase the fancy new items and install them only to have to remove them when it becomes inspection time.
Just be sure what you are purchasing is DOT Approved in your state.
There is another issue with LED LIGHTS causing RFI interference with some electronic/radio/TV items... Being SAFETY lights probably won't an issue with you but being a Ham radio guy I have pulled up behind big trucks with their LED lights on and my Ham radio would would start acting up... Also in my RV trailer that had one brand of regulated ceiling LED lights installed would blank out my HDTV and WX radio especially when I was using the OTA antenna every time I turned on the ceiling lights... I had to replace the LED lights for the non-regulated type to resolve this problem... Just something to think about haha...

There are a lot of locations in the US where inspection is mandatory.
If inspection services operate your tail lights and can see the difference of lumens, you'll be getting a notice and replacing what you have.
LED tail lights have different diffusion characteristics than a filament bulb. I can usually spot a replacement LED/array and original lens from over 100' away.
