This is controlled by a browser and impossible to change with HTMl and CSS. There is nothig CKEditor can do in here.

If you don't like how underline is handled by a browser try to experiment with border-bottom property. E.g.

h1 {
color: #000000;
font-weight: bold;
font-size: 30px;
border-bottom: 5px solid #000000;
}
