A latte score on this site is a milk-workflow score. Automatic texturing ranks above a steam wand, and a steam wand on a dual boiler ranks above a steam wand on a single boiler because you can brew and steam without waiting for the same boiler to change jobs.
Hands-free steam is why the Bambino Plus leads a lot of milk lists even though the boiler is a thermoblock, not a dual boiler. The booklet is the source for that claim.
The Dual Boiler is the opposite trade. Breville’s US page describes a brew boiler and a steam boiler, a 58 mm portafilter, and PID. You texture the milk yourself. The price on the Breville page was captured as a verified snapshot. Other shops on that product are still sample prices, and they are not allowed to undercut the verified one in this dataset.
The Philips 3200 EP3221/40 leaflet describes a classic milk frother, which this catalog stores as a steam wand, and a built-in grinder with 12 settings. It is a super-automatic. The leaflet is a 230 V document, so a US 3200 series unit needs its own spec check.
If the milk system is unknown, the milk score stays blank. That is why a guessed “LatteCrema” is not filled in for every De’Longhi.
