What to make of my current IB internship

I have a very unusual internship (my first) at a boutique now. I'm doing typical ib work (building pitch books, writing company/industry reports, screening and analyzing potential investments, participate in M&A meetings and so forth), but my experience does differ significantly from most ib internships in the following ways: -I only work 40 hours/week -The company outsources valuation, so I am not getting to build models at work (I still do other Excel work, however)

That being said, I am building comp, precedent transactions and DCF models outside of work and the MDs are verifying and correcting them.

So I'm wondering to what extent this overall experience will be considered an asset for future internships and FT employment further down the road. Will interviewers even ask how many hours a week I worked? Would it be unethical to write on my resume that I did valuation, although it wasn't part of the formal work? If they find out I only worked 40 hours per week, would they brush my experience off as some sketch back-office role?

TL;DR I have an ib internship. Only working 40 hours/week, doing modeling only outside of work but it's still being verified by MDs. Is this considered good experience/how do I make the best out of it in interviews and on my resume?

Thanks for your insight
