Its 15% when comparing one value to the other. However, the average protein intake for most people should be between 50-100 grams. This means that in terms of daily value it represents 2-4%. 2-4% is often the error margin in polling because at that point the data is considered insignificant.

It's still significant enough that you shouldn't assume your protein needs are met if you just substitute an egg white for every whole egg you'd otherwise eat, especially where the white makes up around 3/5-2/3 of the egg's mass. Just take out the yolks with no other adjustments, and you've dropped the protein content of the eggs in the dish by ~40%.

Of course, you generally aren't going to make substitutes that blindly, so saying that that's something that needs to be considered is very much stating the obvious.

But whole egg is good for baking, too

They serve different purposes. Sometimes you want whole eggs, sometimes just whites, sometimes just yolks, sometimes whites and yolks beaten separately then mixed back in together... Eggs are tremendously versatile in baking.
