Including foreman_theme_satellite plugin in upstream nightly does not include the header_logo.svg in the branding.
Possibly similar to the below issue for reference: https://bugzilla.redhat.com/show_bug.cgi?id=1609326
From the top of my head, I know that assets replacement mechanism is sensitive to rails' hashing. I think the bug can be presented when rails requests hashed version of the asset, but the theme contained unhashed one, or a version of the logo with a different hash.
$ rpm -q tfm-rubygem-foreman_theme_satellite
$ rpm -ql tfm-rubygem-foreman_theme_satellite | grep header_logo
The header_logo.svg is correctly displayed in the WebUI.
There are still similar warnings in the production.log:
2018-12-17T03:30:06 [W|app|] Plugin foreman_theme_satellite has assets outside of its namespace, these will be ignored: Redhat-logo.svg, favicon.ico, header_logo.svg, login_bg.jpg, login_logo.svg, theme-navbar.png, theme_client_side_branding.js.erb, theme_dashboard.js, satellite/application_colors.css, satellite/bastion.scss, satellite/bundle_colors.css, satellite/login.scss, satellite/patternfly_and_overrides.scss, satellite/topbar.scss, satellite/wizard.scss, theme.scss
I suppose this issue is tracked in the BZ1609326.
