Sorry for the late reply, but this is the discontinuity that I was getting at.Can you use a red arrow to indicate what you're referring to?
I legitimately am unable to discern what discontinuity you're talking about. It just looks like the dorsal intake to me, with its side/dorsal aspects having multiple tones of camouflage overlapping.

If you look at the bigger picture, it would look something like this -- I've tried to illustrate the S-duct and where the engine nozzles ends up. See also @WaterbDoge 's CG which gets at the same idea -- the taper of the dorsal intake should be quite steep at this angle, given that we are almost head-on and that the intake does not appear to widen significantly since it is constrained within the two side engine nacelles in previous side-on photos.

I'm not trying to rule out other explanations, to be clear. But given a combination of past photos of the left side, which have not had these white splotches curving in that way (see below), a liberal estimate that a mirrored image is relatively unlikely, and my understanding of aerodynamics and area ruling indicating to me that the inlet manifold will be more likely narrow rather than wide, this seems to me the most likely shape.Camouflage has a weird way of appearing from different angles (particularly as we don't actually see what the full right/dorsal fuselage white pattern is), I wouldn't put it past the pattern being the same but just looking different because this is the first time we are seeing it at this angle.

Anyways, I'm happy for everyone to keep their own reservations and I'm sure we'll find out in due time (hopefully not too long).
