You make a good point. I found Tennet to be easy to hear but I know there were meme reviews about it being too quiet.

So I looked one up

https://www.theguardian.com/film/2020/sep/03/tenet-dialogue-...

Interestingly in the case of Tenet the claim is that cinemas intentionally were playing the movie too quiet.

It brings up the usual issues of audio mixing and cinema and home is vastly different. But puts Tenet down to cinemas turning it down to avoid loud explosions.

So is this a case of cinemas turning down well mixed movies because movies are coming out too loud?

But really this is just the same problem over again. Sound engineer mixes audio intending for a high end cinema. Some cinemas plays it poorly, people watching at home have no chance to play it properly...
