Do all smart glasses with displays use waveguides?
No. Waveguides are one approach to near-eye display optics. The presence of a visible image in glasses does not identify the internal optical architecture, and different designs can serve different viewing experiences.
Compare the result as well as the mechanism
Ask for the architecture when it matters to integration, then compare the assembled product on the task. A technology label alone does not establish comfort, usable image area or text clarity. Those properties depend on the complete design.
A short-cue display and a virtual-monitor product can both put imagery in front of the wearer while making different optical and form-factor choices. If the documentation does not name the mechanism, leave it unspecified. A lens photograph is not sufficient evidence for assigning a particular waveguide design to the product.
