I'm not sure if there's been a simultaneous release yet where a physical Switch game hasn't been priced higher than the ps4/xbo versions, it's hard to tell as there's been very few cases of this so far.
But looking at Lego City Undercover as an example, it's currently £21.99 on ps4, £23.90 on XBO and £32.99 on Switch from Amazon.co.uk
The cost of cartridges is obviously not that much higher to warrant a $10 increase, but it's probably a contributing factor, no idea what the other factors are though.
