Possibly because some people just like the look of dithering. While it can be done for optimization(and of course that's the original reason it exists) sometimes it is just done for aesthetics.

Please disable dithering, there's not need for it considering extremely low amount of colors that are all basically flat areas.

Artistic intent?

Yeah, dithering can be a method to have specific visual style and it definitely has purposes and I can recall some amazing works with beautiful dithering patterns applied. Just that in here it definitely looks like incorrect export setting, rather than something deliberate, there's dithering with pixel crawling even on letterboxing area.
It's like saving artwork as extremely compressed JPG and saying that's the look you are going for. It can be, but if the context doesn't scream that it needs to be deep fried JPG to get your point and vision across, it just looks bad.

This whole conversation, all I can think about is how Nintendo use dithering in EVERYTHING and I hate it.
Making an object you are too close to fade away doesn't need to have this mesh screen over it.

Dithering looks good on like, PS1.

The reason why old consoles like that use dithering is to provide visually more colors with lower bit depth (I'm pretty sure PS1 almost always uses 16-bit in most games gameplay, where most modern displays are 32-bit). Because when viewed through analog signal, it would blend regardless and look better that way.
That's why on stuff like modern PS1 emulator you can just disable that because you already have higher color depth and resolution to begin with and that's partially why old games look so bad on modern display because they are too "perfect".

And that's kinda still where I'm getting at. Dither in itself is not bad, it's just a tool to make material look like it visually has more color depth to it and avoid banding artifacts when working with restricted palette or color depth (GIF being locked to 8-bit, 256 colors) and because there's not a single way to dither, it can be applied pretty amazingly or even done fully manually.
Just that in here it simply looks like wrong export setting that looks bad still rather than deliberate decision to make it have specific aesthetic.

Speaking of banding, post #3478925 then would've needed dithering, because that banding is super visible thanks to using such high resolution and all the colors and gradients on top on such restricted GIF fileformat. This is then more of general rant, but with these kind of animated content I have started to hope that we would finally adapt newer lossless image format for animations, APNG being currently super widely supported already and WebP and AVIF looking promising, but no, let's be stuck in literal 90's fileformat and 256 colors for modern digital animations made with 16 million colors in mind.
