Hmmm, honestly, if that were the case that Kate looked so much younger without the make up then why wear the make up.
Prior to this, Kate had 3 pregnancies and gained and lost weight and you could see that the weight loss had been a bit ageing in terms of skin elasticity. It would be very surprising to me if she had lost even more weight and then suddenly got much fresher faced.
But maybe you are right. The video quality is absolutely terrible so it could be that. It is clear that Kate knows she is being filmed, so it's very much staged at an acceptable distance. For a lady who didn't want her face seen last week, she seems very happy about it very suddenly!
