DVD and Blu-ray players that do internal decoding of the DD soundtrack (most DVDs and Blu-rays will have a DD soundtrack, plus others, last time I checked a few years ago) are supposed to apply DRC. Some might have an option to change the DRC strength. If you're watching over-the-air ATSC broadcasts in the US, those will have DD (AKA AC3) audio, and the TV should be applying DRC based on the same metadata. Streaming services have taken a massive step backward in this regard. TVs should have better signal processing options for this (and some do). I have a custom "night mode" set up that deals with mixed streaming volume levels in my system, but I'm using highly customized pro audio gear in ways that the average user won't want to pay for or deal with.
