...delta-wing aircraft...
The pic would seem to confirm that, so not the same wing layout at all. Concorde famously sported an ogee wing which gave supersonic performance without compromising low speed lift. The only drawback was the monumental angle of attack required at low speeds for takeoff and landing, necessitating the "droop snoot".
I was sat in an MGB roadster in traffic on the A4 at the 312 roundabout when Concorde went over on final into LHR. When it got about 1/2 mile ahead of me I got pressed down into the seat by the wash off that wing. At high attack angles it creates a sheet of air behind it, confined by the vortices from the leading edges. This acts as an extension to the wing, generating additional lift. You can really feel it when underneath the thing.
