Config.theme empty

I'm trying to access values from config.theme from within partials/navigation.html.twig

Just debugging and trying to display the values. These all display empty. You'd think at least dump(config.theme) would display something. Empty. What am I doing wrong?

{% set theme_config = attribute(config.themes, config.system.pages.theme) %}

theme_config: {{ dump(theme_config) }}<br>

config theme: {{ dump(config.theme) }}<br>

theme dropdown: {{ theme_config.dropdown.enabled }}<br>

latierra dropdown: {{ latierra.dropdown.enabled }}<br>

dropdown: {{ dropdown.enabled }}<br>

Yes, you're exactly right. I wrongly assumed that dump() displays results in the HTML. var_dump() displays results in HTML as you stated and I was able to track bugs this way. Thank you!
