Safari’s Request Desktop Website can request a desktop presentation when available. Your iPhone does not become a PC, install a Windows program or acquire a different account type. Compare the visible content, not the label of the selected mode.
What the Safari option actually changes
Safari provides Request Desktop Website through the Page Menu when available. The supporting Apple guide is available at Apple’s Safari guide to requesting a desktop website. The site may respond with a layout intended for a wider screen, but the result depends on that particular webpage. Some pages may look different, while others may appear almost unchanged.
Worked comparison: a hypothetical table
Hypothetical example, not a live-device test: imagine the same reference URL first displays a table in a narrow, stacked phone layout. Each row places a label above its value, so the information reads vertically. After you request the desktop website, the same table is shown as a wider grid, with headers across the top and values arranged in columns.
Compare identifiable cells and headers. If the phone view stacks “Room” and “Status”, while the other view aligns those headings above columns, describe that arrangement change. Do not claim a “Time” column was added unless it is actually visible.
If both views show the same headings and values, record no visible change. The page may serve the same layout. That observation alone does not demonstrate a fault.
What this comparison cannot establish
A wider table is evidence of a display difference only for the observed page and request. It is not proof that every page on the site will respond in the same way. It also cannot establish that a mobile restriction was bypassed, that a game can be used on a computer, or that software was installed.
Keep the same URL in both observations and compare identifiable headers and cells. Do not convert an unfamiliar layout into a claim about changed rules or confirmed hidden columns.
