You two must have not payed any attention when watching the show. The D.E.O moniters ALIEN threats, they have never cared about any metas until Kara needed help against one, then Hank was sympathetic enough to help. I assume though, that just like Barry, it was impossible to get a picture of Earth 3's Flash. Cat only managed to get a picture of Barry because he was running up her building. Point is that Jay was probably secretive about his crime fighting due to being able to save the day in the blink of an eye.
