That doesn't answer my question.

Does the PlatformBootManagerLib instance that is *specifically* linked
into BdsDxe in *your* firmware platform call BootLogoEnableLogo()?

Build your firmware with "--report-file=report.txt", and look up the
following part:

Module Name:          BdsDxe
[...]
Module INF Path:      MdeModulePkg/Universal/BdsDxe/BdsDxe.inf
[...]
Library
[...]
<IMPORTANT-LINE-HERE>
{PlatformBootManagerLib:  Time = ...ms}

The pathname just before the "PlatformBootManagerLib:  Time" line gives
you the INF file path that is relevant. Check the C files listed in that
INF file, for a BootLogoEnableLogo() call. The call should be made in
PlatformBootManagerAfterConsole().

Thanks
