On the Sony KD-X7000G, it has a power saving mode, Low/High/Picture off. I run it on Low most of the time which is a slight decrease in the LED brightness. I notice when the PC screen saver blanks the screen, the LED backlights dim down very low to save more power. At the moment the brightness is on 37 (max of 50) and contrast is 83 (max of 100). This is for webpage use and youtube.
If I were to watch a 4k HDR movie (which is rare), then I would turn the power saving mode off and have higher brightness.
Not running the TV at full brightness all the time would surely extend the life of LED LCDs. I'm talking consumer grade sets.
I have had some experience with commercial grade screens (not TVs) at work, and have noticed on some models the LED backlights fail after 5-7 years, these screens run between 16-24 hours per day at high brightness with poor ventilation, they get hammered. The majority of the heat radiates from the front of the screen, they are only 27 inch in size, and are expensive, maybe 2-3k australian.

Some fifteen to twenty years ago, they had upwards of 100k hours of rated life - with an estimated half life of less than that. Various manfacturers played gamesmanship with those types of specs. The half life simply means the age-out of the plasma cells ends up resulting in the dimming of the panel by half.
A lot of predictive math went into those numbers to be fair... but things like "panel lottery" tied to production runs; cranking down the brightness setting from first use and proper air flow (cooling is super important for plasma reliability) - can all mitigate aging factors.
Honestly not sure where the last designs advanced to before the tech switch to OLED, but I sort of recall that there weren't leaps & bounds of improvement reached.
A lot of plasma panels would age out more in spots at as low as 30k hours of run-time. Cheaper ones or poorly treated ones would exhibit RGB decoupling, lending itself to what was called "pink spotting". Pioneers were notorious for that failure.
If the entire panel of "cells" are treated gently, and with little luck sprinkled in there too, then the uniformity can be maintained for a considerable amount of time.
Brightness is an in-the-eye-of-the-beholder, subjective thing and a uniform drop in peak brightness ain't as bad as it sounds...

The first new TV I bought was a 32" Vizio Plasma for $500 back in 2008. I sold it to a friend in 2013 for $100, I think a year or two later it wouldn't turn on. Bulgy chinee capacitors on the power supply board. I recapped it for the cost of parts and as far as I know it still works today. Was a nice little TV and looked a hell of a lot better than the LCDs at the time.
