Update theme-color meta without page refresh

Question

I am unsure whether this is possible; we have various theme colors (colours...) and they change with each page. We are also utilising a lot of content loading without page refreshes.

I want to use the theme-color meta tag that is available in in chrome mobile browsers to set the tab colour.

As our pages do not refresh, i would like this color to reflect the new page background colour. I can remove the original meta and add a new with the following;

function updateMetaThemeColor(theme) {
    var themeColor;
    if(theme == 'theme-1') {
        themeColor = '#f4dcdc'
    } else if(theme == 'theme-2') {
        themeColor = '#f0e8dd';
    } else if(theme == 'theme-3') {
        themeColor = '#d5e7f0';
    } else if(theme == 'theme-4') {
        themeColor = '#f6efb9';
    } else if(theme == 'theme-5') {
        themeColor = '#eaeae8';
    } else if(theme == 'theme-6') {
        themeColor = '#f8e3c7';
    } else if(theme == 'theme-7') {
        themeColor = '#cde8e8';
    }

    //remove the current meta
    $('meta[name=theme-color]').remove();
    //add the new one
    $('head').append('<meta name="theme-color" content="'+themeColor+'">');
}

This does work, in that it removes and reconstructs the meta tag, but as i feared, this change is not reflected in the page itself on Chrome mobile browser.

Is there a way to force the mobile browser to have another look for the meta tag and change when necessary?

Thanks

It actually looks like the approach above does work exactly as it should. Guess i should test better, huh.
