Working for me here - info: Windows 10, C4D R20, Corona 4 daily build from Jan 24th.
I had a Beauty pass with 0 denoising, and a Virtual Beauty with 1 denoising, and rendered locally, and then using Team Render to Picture Viewer. In both cases, local and TR, the Virtual Beauty was denoised while the Beauty pass was not (though of course I could use the VFB to add denoising to the Beauty pass).
