Yeah, that's a fair criticism.
A lot of it is intentionally by-the-books twee that ticks off all the proper genre boxes. Which is great for the twee fans who probably constitute like 90% of their audience. But for everyone else, it's kind of like "What's different about this as compared to 10,000 other girly twee bands over the last 20 years?" Nothing. It's well done but in such a formulaic way that it's welldone-ness is not particularly interesting and probably not much of a technical/musical achievement.
I think you have properly identified the two stand-out tracks which offer something nice for the more general listening public.
