Is my sister jealous of me?

My sister has always been the prettier sibling, she has blonde hair, implants, etc. Recently, I lost 30 lbs and have been looking better than I ever did before.

Couple steps back, my mom posted a national daughters day appreciation post and chose to use an old (uglier) photo of me rather than a recent beautiful updated photo- even tho she was sent the recent photo a few minutes before she made the post. I confided in my sister of how much this bothered me but she told me that she thought I looked fine. I thought this was hypocritical because the photo of her on the post was photoshopped to the T. I personally thought it was weird how she was bothered by the smallest details in her photo but she never saw anything wrong in my old ugly untouched photo.

Back to now, I sent a video to my sister how my hair was naturally curling, she seemed happy for me. But the following night she sent an old photo of all of us and again that bothered feeling came again. I can tell she photoshopped herself but I could be wrong.. but all I’m thinking is, did she do this out of spite? Are these jealous moves or is it just in my head?

The first three photos are screenshots from the video i sent her showing my hair, and the last one is the photo she then sent me. I’m on the far right and she’s on the far left.
