There is still hope Sony isn’t lying about 15stops.
As I stated earlier it's not possible to "lie" about DR because the figure depends on a completely arbitrary cut-off point for the noise floor, depending on where you consider the noise to start dominating, what resolution you normalise to etc. For every cut-off point there is a corresponding DR figure. Since Sony have not shared which cut-off point they used to obtain their figure it is both completely plausible, and completely meaningless.

Sensor design and pixel size does play a role in diffraction. I agree it is mostly about the lens -- how much stopping down improves abberations vs. increases diffraction. However, pixel size and wavelength of light plays a role
Sensor design plays no role in diffraction it is an entirely optical phenomenon, the only thing sensor design influences is your ability to detect diffraction. Wavelength plays a role I generally use the values for green light as a suitable approximation.
