Not generally, since the supported raster resolutions are usually less/lower than the printer's supported resolutions.

AirPrint *does* require firmware updates for broken implementations and security issues, so just because this printer isn't reporting everything doesn't mean it won't get a firmware update.

Can you try the following test:

{
    NAME "Get urf-supported"
    OPERATION Get-Printer-Attributes
    GROUP operation-attributes-tag
    ATTR charset attributes-charset utf-8
    ATTR language attributes-natural-language en
    ATTR uri printer-uri $uri
    ATTR keyword requested-attributes urf-supported
    STATUS successful-ok
    EXPECT urf-supported
}
