Comment (by tommusrhodus):

 I have tracked down the issue to {{{wp_get_global_stylesheet()}}}
 https://github.com/tommusrhodus/WordPress/blob/master/wp-includes/global-
 styles-and-settings.php#L107-L117

 In the above lines, the function checks if the theme has {{{theme.json}}}
 and if it declares {{{add_theme_support( 'experimental-link-color' )}}},
 if a theme does neither the function does not merge the theme variables
 into the default variables.

 The result is that theme declared variables which share names with WP
 Presets, do not overwrite those presets unless {{{add_theme_support(
 'experimental-link-color' )}}} is declared in the theme.
