Vibrant visuals still not working on one UI 8.5

I'm using a Samsung Galaxy S25 Ultra running Android 16 and One UI 8.5, with Minecraft Bedrock version 26.52.

The Vibrant Visuals graphics mode is greyed out in Minecraft's settings, displaying the message: "Vibrant Visuals & Ray Tracing requires a supported device and compatible Marketplace content."

My device should meet Minecraft's published hardware requirements for Vibrant Visuals.

To rule out conflicts with other add-ons, I created a brand-new world with only the Ultra Vibrant Visuals resource pack enabled. However, the graphics settings remained greyed out, and Vibrant Visuals was still unavailable. The issue also occurs in Minecraft's main settings, outside the world.

I understand that Minecraft bug report MCPE-239742 was marked resolved, with a fix included in Minecraft Preview 26.40.31. However, I'm still experiencing the same issue in version 26.52.
