I'd say The Wire & The Sopranos changed peak television exponentially more than "24" did.....they brought a prestige to television that showed writers/directors that television could be a higher form of art than it had been previously. 24 just kind of upped the game for trashy network shows, while still being in that vein. (Imo)
As for TV vs Movies....there's greater art being produced in either medium now than ever before, it's just a matter of what you choose to consume. If you're only watching movies that get released in theatre, then you're likely to have a bit of a distorted view of the calibre of films being made (and feel over saturated with Superhero/Star Wars/sequels)....but even then, with the slightest bit of effort there's piles of great, challenging stuff available to see in theatres.
I haven't really found any prestige television that's blown my doors off of late, not since maybe Fargo season 2.......plenty of stuff dressed up like peak TV that follow the same blueprint, but fall short of the real deal (Ozark, Narcos, etc etc...that while being plenty entertaining, aren't really close to the calibre of Sopranos/Wire/Breaking Bad/Mad Men etc).
Fact is tho, there's just more of everything....good & bad....just need a better filter than ever before to sift through it all to seperate the great from the good, and the good from the trash.
