Not entirely true. Ultrasound actually has pretty good sensitivity for pneumonia (88%) and even higher if you look at the “difficult” cases requiring CT in the Cochrane review I link to below.

For a predominately peripheral airspace disease like COVID-19 ultrasound should theoretically be very sensitive. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5279077/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5279077/
