Just to confirm I poped in my JP ps4 version and compare it to the JP switch demo. The Switch version have lower res sprites in comparison; you can see some artifacts on diagonal edges that are not found in the ps4 version. Guessing they use the same sprites for 720p mode even when docked and output at 1080p. Disappointed but not unexpected, now I am worry that other dev will do the same for all the 2D games like wonderboy.
