Compatibility of Liquid Glass Effect on Older Apple TV Models

Hello everyone,

Following the WWDC 2025 announcement of tvOS 26 and the introduction of the new Liquid Glass effect, Apple published a press release mentioning that Liquid Glass is "available on Apple TV 4K (2nd generation and later)".
This seems to exclude both the Apple TV HD and the 1st generation Apple TV 4K, even though both devices remain compatible with tvOS 26.

I’m wondering:

  • Will using UIGlassEffect or glassEffect(_:in:) on these older devices cause a crash?
  • If not, will the effect fall back to a simple blur, or render as fully transparent?
  • Is there an API or recommended way to detect whether the Liquid Glass effect is supported on the current device?

Thanks in advance for your insights!
