Yes on the specifications — several times the video bitrate and lossless rather than compressed audio — and how much that shows depends on how large the image is and what the sound comes out of.
The measurable part
A UHD disc carries video at a bitrate several times what any streaming service delivers, and audio that is losslessly compressed rather than lossily. Those are format specifications, not claims.
The part that depends on your room
On a three-metre projected image, the bitrate difference is visible in exactly the scenes compression handles worst. On a 55-inch television at three metres, it is much harder to see. The audio gap follows the same rule: through a soundbar, modest; through a receiver and five speakers, obvious.
What a disc also gives you
Independence from licensing. A film removed from a service is gone; a disc is not. For anyone with a collection, that is often the stronger argument.
The honest case for streaming
Convenience wins for most people most of the time, and this site will not argue otherwise. The disc is worth a box when the system is good enough to show what it carries.
Questions people actually ask
Where is the difference most visible?
In scenes streaming compresses worst: smoke, rain, water, dark gradients and fast camera movement. On a bright static scene the two are close, which is why comparisons using the wrong scene are inconclusive.
Is the audio difference bigger than the picture difference?
On a system with a receiver and real speakers, usually yes. Discs carry lossless Dolby TrueHD and DTS-HD Master Audio; streams carry compressed versions of the same mixes.
