So I didn’t think this sounded right from my experience and checked the UK store (where I am) and it is as you’d expect, all digital purchased games are generally cheaper by £8 - £10 than a physical released. Some older Switch 2 games are priced the same for both physical and digital though.
Just wandering, have you possibly misread the prices the wrong way round. As the prices you listed seem like it would be right if they were reversed.
This is on the official Nintendo site and other retailers selling physical maybe even cheaper.
