Why is OpenCL support is disabled on my laptop if it is supported by the GPU?

I found out OpenCL is used to speed up processing of large spreadsheets on Calc but I can’t enable it, as after restarting LibreOffice, the checkbox is unchecked again. From what I’ve read, this means the GPU is not whitelisted because the GPU driver supposedly doesn’t support the API, but according to GPU-Z, this integrated GPU does support OpenCL:

When I hover over OpenCL box, it says:

Supported Version:  Full
Supported Profile: OpenCL 3.0 NEO

So I don’t get why is the device blacklisted, what’s exactly preventing LO from whitelisting the device ir order to enable OpenCL?

Here’s software and hardware info about my system:

CPU: Core i5-1135G7
GPU: Intel Graphics Xe 80 EUs
OS: Windows 11 Home version 23H2
GPU driver version: 31.0.101.5382

I will, thanks.

The GPU supporting OpenCL in general doesn’t mean it would support it correctly as Calc needs it. There are some devices/drivers/versions on the DenyList (which your’s apparently is not) because they have shown to produce wrong results or lack some features. If a device is not on the DenyList it is tested if activated and if that test fails it is denied.
