Object reflectiveness in AR mode differs between webxr and scene-viewer.

Description

There are differences in object reflectiveness in AR mode between webxr and scene-viewer. WebXR uses the environment-image provided and has high reflectiveness, whereas scene-viewer appears to have little or no reflection, and does not use the environment image provided. Also similar with quick-look on iOS.

Indeed; ARCore's lighting estimation isn't high-res enough to make shiny things look shiny - this is a problem for Scene Viewer and also for WebXR if you enable xr-environment. ARKit does a better job, but generally has a different estimated lighting feel as well. Not much we can do about it from here, sadly.

I came here looking for a solution to this reflections limitation issue also. Webxr does an ok job with reflections, but we are then missing the snapshot/capture function that scene-viewer provides. Is there a way to overcome this? Thanks.

Ah yes, that's been on the list for some time. A PR would be very welcome, not sure when I'll have time to tackle that.
