Mantra/Karma both unhide the vm_image_exr_dwa_level (DWA Compression Level) parameter if DWAA or DWAB exr compression is selected, and lets you change the compression level from the default of 85 - but in COPs (both latest Copernicus 20.5.550, and old COPs, at least since 19.5 it would seem), that option never appears, and if I add it manually from the Render Properties tab, it gets ignored - COPs seems to always output at 85.

Is there a way to set the compression level in COPs correctly, or does this seem like a bug?
