The bumper...I don't know what it's called...that little clip with the snow that fades in and reveals the logo.
It's terrible.
For one, a lot of people actually don't know what TV static is. Analog broadcasts stopped almost 16 years ago, and before that, most younger people had cable.
For another, static is really difficult to compress. It looks horrible and consumes way too much bandwidth for just a couple of seconds that won't even load right. If anything, they should cache a local copy of the bumper in-app in a format that doesn't look like ass when every pixel changes every frame.
The 1984 Gibson novel Neuromancer begins with the line, "The sky above the port was the color of television tuned to a dead channel."
At the time, this unambiguously meant the speckled gray of analog TV static: radio noise amplified and played out through a CRT's scanning electron gun. However, before too many years had passed, new TVs started displaying a solid blue screen when tuned to a dead channel.
And in 1996, Neil Gaiman riffed on Gibson's line, in Neverwhere: "The sky was the perfect untroubled blue of a television screen, tuned to a dead channel."

That's the neat part, people don't know what it is, and will find out the history of it if they decided to look it up. There's a reason Marvel's intro where they flip through all the comic book is so popular and recognizable, it's their history.
I wish marvel would go back to that... Nowadays with the juggernaut that is the MCU we have that weird CGI intro for "MARVEL STUDIOS" that shows clips from previous movies.
NPR did a podcast on those "bumpers" (there's a term that I don't recall). HBO wanted to change theirs for the reason you indicated as well as the fact that it was rather long compared to Netflix's and others.
They paid a lot of money to develop others and also do testing\ polling with end users. The original beat out all the rest because it's been their bumper for so long.
I always thought it was an apt metaphor for HBO as a service. Starts out analog and low resolution (because of the compression issues but it helps the visual) that clarifies what it is before having proper branding arrive. As a former user of HBO Go and HBO Now, it's nice to see them finally find their identity.
HBO Max, for the brief period of time it existed, had a more fitting 'bumper'. Hacks, which started out as a 'Max Original' still had it in season 3, but The Penguin, which was a Max Original until it wasn't, has the fuzzy version (I've had players that struggle with it a bit, but I doubt HBO gives a shit about the quality of my experience pirating their stuff)
Video codecs mostly work by tracking movement, predicting which pixels will change, and striving to only encode the pixels that actually change or change dramatically. In other words, compression looks for patterns.
All of that goes out the window when you try to compress static. There are no patterns. It simply can't be compressed. This isn't a matter of the algorithms not being good enough. It's a fundamental limit of information theory.
Anything fancier amounts to embedding the intro into the compressor as a well-known pattern. And at that point, you're better off just caching a 4K version of the intro as a standalone video file directly in the app.
Why not just have the app dynamically generate the static with random numbers every time. There is no video file of white noise, and bonus the bumper intro is never exactly the same twice.
