Lesser is a morph that can already have a lot of yellow/gold in it, especially when they are young/little, so it isn't as obvious if it has pastel or not as some other combos. The faded head can be a big clue. Also, I'm not sure all pastel lessers have this, but at least a lot do. You can see it on Doolittle's pics. The lower sides are more yellow than white. From what I can see and also your own words, they are white on yours. So, I'm in agreement with those that think she's just a lesser.
