It would bother me, but a picture lighting might be emphasizing it. All that said, it wasn’t that noticeable to me until you pointed out where in the picture. You’ll be in a hurry to open and close your bag and never notice once you start wearing it,
H large and small means a lot of your hard earned $. If it’s going to change how you feel about the bag every time you go to wear it, unless it is a dream color, and you LOVE the bag, saying something respectfully is doable. Such as you love the bag, but the interior flap has you concerned before even a first wear. Are there possibly any other colors we can consider if we can’t get another identical color? Plus you only get store credit, so you will find something else with your SA sooner or later! FWIW, I returned my first H bag purchase and worried it would stop me from getting other bags. My SA helped me find other choices and the journey down the rabbit hole continued.
