TV has been on a steady increase for the past 10 years, and I'll argue a lot of TV from the 90's helped pave the way for that.
For me, it starts and ends with Twin Peaks (and I'll forever talk about this show, so allow me to explain and justify it here).
It was basically the brain child of Lynch and Frost, Lynch who had made his name in Cinema and Frost who had a number of successful TV episodes under his belt. It was seen as the first time someone from Cinema took a "Step down" and worked on TV (Although I don't know how true this is, this might have been the first time it was successful). This started the trend of which I call "Cinematic TV", simply where TV itself took a form more notable to it's Cinematic counterpart, stories were larger and the cinematography was much more experimental in nature.
Shows like Star Trek were already doing this on the Sci-Fi end of things, and this helped pave the way for shows like Babylon 5 and Farescape, to eventually shows that are on Netflix and Amazon (I'll get back to this in a minute).
I think X-Files, while t takes a lot from the DNA of Twin Peaks, also took a lot from the Sci-Fi boom of the 90's, in many regards, it was at the start of it.
However, I think the true successor to Twin Peaks was HBO, in a more direct and confusing way, it was Oz that helped bring in a lot of the ideas that Twin Peaks started in terms of production and effectively pave the way for HBO to experiment with new ideas.
In many regards, British TV has also always been a big influence, taking shorter seasons and making them more compact. Eventually Utopia would be released, which feels in many ways as a bridge from Twin Peaks to Mr Robot, a show which effectively feels like one long movie.
Finally, we come back to Twin Peaks, at least with Season 3, which in on itself is one long movie. To me, with the conclusion of this show ended the first step for Cinematic TV, the bridge between both has finally been complete.
The second step, in my opinion, started with Wandavision, now we're getting Cinema level budgets on streaming services, something which is seen as being ridiculously expensive but never the less pays off.
I think it helps that these seasons are shorter, giving you the best of British TV where seasons would usually last around 6 episodes.
Even if the Disney Marvel shows aren't your thing, compare it to any of the CW shows and you can tell there's a lot of budget and work that was put into this show.
Going back to Twin Peaks for a minute, David Lynch has said there is more room for ideas and experimentation in TV than in movies. In movies you are confined to a 90 minute to 3 hour run time, and while the budgets are bigger, you don't get any time to really express your ideas. TV can last anywhere between 6-20 episodes and so you can have an episode which is just a nuclear explosion for ten minutes.
So I think TV has certainly become more respected now, it helps that we'e in the age of streaming services where shows can get away with a lot more violence and swearing.
We'll still have shows like NCIS, a show which is incredibly formulaic and very bland looking, and while I'm not a huge fan of the Colour grading in the Disney shows (in the MCU in general, be more colourful, you're comic book movies, not Saving Private Ryan), I can certainly appreciate that a show like Loki has a better hand at sets and costume and making things look big.
