Possibly. The box should emphasize that it is digital only. This is far more "mainstream" than the Xbox One SAD and so could lead to further complications.
Honestly, they should have pulled a Nintendo Wii U era and released the more expensive one in black or grey. Make it easier to distinguish. Maybe even invert the colore.
My other concern as mentioned is the storage. I know MS has cards that match the SSD speeds and external HDD support for One games. I know Sony has planned support for all external HDD/SSD, but will they be able to run games like Ratchet or will people have to move over? This is where leveraging the cloud and new compression techniques come in handy and I believe Sony has a good one.
Anyhow, that was a bit of a tangent. For my opinion is someone working towards a BCOMM in Marketing, it's a problem if they don't do a good job distinguishing. Having them look 90+% identical was a mistake and they should have colored one grey or black or inverted the colors. Still, it all comes down to the commercials and the box.
