If you're mapping an SDR image to cover the whole screen, then yes I agree.

The issue appears when the SDR image is mapped to be part of an HDR image (e.g. as picture-in-picture on a video stream) or alongside an HDR image.  The presence of specular highlights will affect the shadows and mid-tones perception of the scaled SDR image - the peak brightness will look correct.
