I love Westworld to death and saw it the first time with headphones. Now I’m rewatching it with my wife with the TV + sound bar and boy does this get on my nerves. I have to sit there with my hand on the volume control so as to not piss off our neighbors the entire time.
Be sure you're listening to the stereo feed and not the surround. You'll need to tell your streaming device to request the stereo feed.
Old movies have a constant level of audio. Current movies audio levels are like a sine wave.

Blame your TV, not the content. Or, blame yourself if you like for not buying a soundbar or soundsystem.
A lot of TVs these days have Night Mode or the like. That's the fix!
PS Downvoting me for... What exactly? Because I told you two solutions and neither of them are what you prefer? TVs are literally paper thin and physically can't have good speakers except for special cases in the high end. Buy a soundbar, even though they suck and apparently people these days are scared of plugging one more cable into something, or get a stereo system for the same price and plug in two more things (speakers) that can fit anywhere on your wall or whatever.
