Am i too sensitivev Boyfriend said picture “wasn’t screenshot worthy”

My boyfriend has been asking me to send him nudes since I’ve been on vacation. It’s hard to do since most of the time I’m out or I’m at the room with my mom and she doesn’t condone that. I just sent him a bikini pic of my booty and I thought it was good and I asked him why he didn’t screenshot since he’s been wanting me to and I went out of my way to do it he said “wasn’t screenshot worthy”. Am I being too sensitive? Is that not just overtly mean and rude? He almost always screenshots everything but sorry if I don’t go out of my way to get an A1 nude while I’m on vacation for 2 days.
