With V-Ray 5.0 the Maya Bifrost renders physically correct, i.e. it appears darker. The original look from previous V-Ray versions can be replicated by adding the V-Ray fluid legacy Phoenix FD shading attribute and then turning on the Legacy Phoenix FD Shading option. See the Rendering with Older Assets page.
