There's nothing in jQuery, and nothing straightforward even in javascript. Taking timofey's answer and running with it, I created this function that works for getting any properties you want:

// gets the style property as rendered via any means (style sheets, inline, etc) but does *not* compute values
// domNode - the node to get properties for 
// properties - Can be a single property to fetch or an array of properties to fetch
function getFinalStyle(domNode, properties) {
    if(!(properties instanceof Array)) properties = [properties]

    var parent = domNode.parentNode
    if(parent) {
        var originalDisplay = parent.style.display
        parent.style.display = 'none'
    }
    var computedStyles = getComputedStyle(domNode)

    var result = {}
    properties.forEach(function(prop) {
        result[prop] = computedStyles[prop]
    })

    if(parent) {
        parent.style.display = originalDisplay
    }

    return result
}

The trick used here is to hide its parent, get the computed style, then unhide the parent.
