Odd Xpro2 OVF behavior w/ image display

Wondering if this is a bug. When using the 'image display' setting (either .5 or 1.5s) with the OVF the image shown after taking a shot is very dim. If you review the image normally in the EVF the exposure is as shot.

This works fine on my x100f. Is this a bug in the xpro2 firmware or am i missing a setting somewhere?

thanks!
