With those large lobes they don’t look like Aglaonema to me either. ‘Hilo Beauty’ would have basal ribs, the central vein in each lobe, which I don’t see in the photo by @RuuddeBlock.
They look a great deal like Schismatoglottis neoguineensis, a synonym for Dukaruk (Schismatoglottis calyptrata) which has highly variable leaf markings or none at all.
