Sent photos not showing in info section of a person’s contact- indication of being blocked?

I’ve sent someone pictures and they show in the info section for a few hours after being sent but then disappear. I’ve seen nothing online about this meaning I am blocked but it never used to happen with this person. I can still see their focus status and links they have shared in shared with you which I’ve seen is an indication I am NOT blocked but it feels odd the pictures I sent are disappearing from info. My texts are still being delivered as iMessages but I’ve read that’s not a good indication to tell if you’re blocked or not.

My question essentially boils down to is this just a coincidence or is it an indication I have been blocked

Thanks
