poor image quality on Hulu specifically on Apple TV

[ignatius345]

I have an Apple TV 4K (3rd generation). I'm having a weird issue with Hulu (and only Hulu) where everything I'm watching on my 4K TV looks low-res and blurry -- like 720p or worse. Other streaming apps are working fine.

Stuff I checked:

• every title I stream on Hulu on my Apple TV looks like crap
• my internet connection is very fast and stable
• other streaming apps all stream at high quality
• streaming the same show on Hulu in Safari on my Mac, on the same wifi network, looks fine
• I restarted the Apple TV of course
• I deleted and reinstalled the Hulu app

This is driving me crazy. It's clearly an issue with Hulu on the Apple TV specifically but I can't figure out what. Posting on the off chance anyone else is having the same issue. If Hulu was having issues with bandwidth generally, I think I'd be seeing it on my Mac, but it's only on the Apple TV. Possible some bugginess with their app?
