My (30F) boyfriend's (34M) sister (32F) makes remarks that have subtly bothered me, frequently recently. Do I bring it up to my boyfriend or let it go?

In an attempt for me (30F) to get closer to my boyfriend's (34M) family (whom he's very close to), we've been spending more time with his sister (32F) and her husband (35M). We've been together for more than 2 years now.
However, a series of interactions this past month has started to make me hesitant to spend more time, but I also want to give his sister the benefit of the doubt, as none of it feels intentional. I think she's just blunt, and I don't want to be "too sensitive". A couple examples:

• I gifted her a nice self-care set (sheet masks, bath bombs, etc.) for her baby shower, that was definitely on the pricier side, but not a popular brand since it was an all-natural beauty product brand. I very intentionally chose this brand given she's pregnant and checked all the ingredients on the list to ensure it was safe. She opened the gift and said "I should be able to use this now, it's not any of the boujee stuff" like x brand or y brand, implying that only the expensive brands would have active ingredients she couldn't use. The gift was spendy, at the same price point as the other "boujee" brands she listed
• Her husband was laid off at work awhile back, and has been unemployed / really actively job searching given the baby is coming soon - I work in the same field as him. My boyfriend mentioned that I recently had a new job offer and was considering taking it, to which his sister says - "well that makes sense because you must have been a diversity hire. No offense, but you know women in tech are diversity hires." I graduated from a top university and to be honest, am definitely NOT a diversity hire. I know she's a little upset that he still hasn't found a job, but still.
• My boyfriend and her husband were roommates during grad school, therefore, the three of them spent a TON of time together before I even met him (all went to the same school, she obviously stayed overnight there very often), during which my boyfriend also had other prior relationships. She's been bringing it up often - "remember when you dated x and we all went to ... ". Comments started out innocent and seemed to just genuinely be past memories / reminiscing over old times (e.g., talking about a halloween party they went to on halloween), but they've recently gotten to be less innocent, like: "we used to hear you and x talking through the walls at like 3am" or "Dad really liked when you dated y"

These are just a couple examples. In standard Dating.mobi fashion, normally I'd just talk to him, but my concern is that a) he's really close with / protective of her and b) he's mentioned multiple times that she's just blunt / that's just her personality, so I wonder if I should just not take it personally.
TL;DR Boyfriend's sister makes a lot of inadvertently hurtful comments. No one else has called her out on it, and it seems that is the way her personality is. Should I accept it and work on myself to not let it get to me or bring it up to my boyfriend?
