To clarify, updating the PolyHaven HDRI size will change the size of the textures after a restart:

I will not update the HDRI images/textures you are currently using in your scene. You can check the actual size here, but I should also display the HDRI size more prominently in the UI.

If you want to use the larger size, reapply the HDRI later.
I hope that clarifies things!
Regards,
Thomas
