The image you posted above is not Oncidium Dancing Sunlight. There are two differences that I see right off the bat.
In Oncidium Dancing Sunlight, the two side lobes of the lip, one right and one left of the cinnamon blotch on the lip, are much fuller and broader then the ones on arctangents flower.
The second difference I noticed is the little hooded column in the base of the lip. Dancing Sunlight's is much smaller looking like a little hooded monk. Acrtangents Oncidium has a larger hooded monk. Notice how green it is in the center.
What do I think about arctangents image? They are both hybrids of Oncidium, now Gomesa I think, varicosum. There is a variety of that Oncidium species called Oncidium varicosum 'Rogersi', that had fuller petals and sepals plus a larger lip when compared to the regular varicosum.
Unfortunately so many of these Oncidiums look so much alike due to the varicosum parent. I would be careful in making ID's without experience with this group.
