Yes, lovibond is a measure of color, which is created by kilning the malt. The longer you kiln, the higher the color or lovibond, and the more sweet flavors it creates.
Crystal, for example, is 2row that has been kilned longer. It leaves an obviously sweet or caramelly taste, even at only 5% of the grist.
Crystal is not just 2 row that's been kilned longer. It's a different process from regular malt.
The terms Crystal malt and Caramel malt are used interchangeably to describe a type of grain that undergoes a special stewing process during malting resulting in a crystalline sugar structure inside the grain's hull. These grains give a sweet, caramel flavor to the finished beer and can almost always be used as steeping grains by extract brewers. This type of specialty grain can be easily made at home from any base malt.
The crystallization/caramelization process
To make crystal or caramel malt, maltsters take green malt and, instead of heating it in a dry kiln, stew it in an extremely damp or wet oven. In the presence of water, each kernel of grain essentially undergoes a mash in the hull, converting the grain's starch to sugar. However, since the grain is not crushed, the sugar does not go into solution and create wort. Instead, when the temperature is lowered, the sugar crystallizes in the hull, giving the grain the appearance of a crystal of sugar. The malt is then dried over heat, with the drying temperature and time determining the color and flavor characteristics of the finished product.
Brewing with crystal and caramel malt
Because the stewing process essentially mashes the grain, crystal and caramel malts are some of the few steeping grains that can be used in extract brewing without needing to be mashed, although some of the palest crystal malts may not be sufficiently converted and may leave haze in the finished beer. All-grain brewers may also simply add crystal malts to the mash as they would any other specialty malt.
Because their other options are limited, new brewers brewing extract batches often depend on crystal malts, sometimes to excess. While crystal malts in small amounts will give a sweet malt character to the finished beer, in excess it can create a cloying or artificial character. Crystal malts also add to a beer's body and increase head retention.

Furthermore, higher kilned malts don't necessarily make the malt or beer sweeter.
