Not for me. The Ditra is already waterproof, Alex. What you're trying to waterproof is the gap between the Ditra and the tub face. Putting KerdiBand over the Ditra won't help. You need to fold the KerdiBand up the face of the tub and bond it to the tub with the Kerdi Fix.

Just using a caulking or flexible sealant such as KerdiFix alone in that gap would not be sufficient in my opinion. But, again, entirely up to you.

You would also want to apply a bead of sealant, most likely one color matched to your grout, between the tile and the tub face. That is not for waterproofing, that's just to fill the gap you have there and provide movement accommodation.

My opinion; worth price charged.
