About 10 years ago the Air Force changed the color vision screening to the computerized random Cone Contrast Test (CCT) you are referring to. It was developed, I think, by an Air Force ophthalmologist at Wright-Patterson AFB (I think) in Ohio. He sold the Air Force on the fact the CCT can measure color vision capability very minutely. The other services have declined to use it to my knowledge. I had heard when it first rolled out many successful, current and qualified pilots were failing it during initial tests. Once it got approved for actual Air Force color vision screening, many previously pilot qualified UPT candidates were disqualified (around 2011/12 I think).
While at USAFA in Aug or Sept 2019 at an AOG conference, I asked the Sup at the time, Lt Gen S...., and Director of Admissions, Col ???, what was going on with it. They both described going to the Air Force-Navy football game in the fall of 2017 or 18, (again, I think one of those 2 years, but it was at Navy I believe) and during the half time show they introduced the 4 F-18 pilots that did the pre-game fly-by. According to their story, 2 of the fly-by pilots opened their flight suits to show off their USAFA graduation t-shirts, but were both NAVY Lieutenants (as in O-3's). General S and Col ?? tracked them down and asked what was up with that? The two USAFA grad Navy F-18 pilots explained they cross commissioned so they could attend Navy pilot training since they could pass the Navy color vision test, but not the new Air Force CCT. General S said he was quite surprised and unaware of how the CCT was disqualifying prospective UPT candidates, explained what was going on to other Air Force leadership, and secured a very small relaxing of the CCT standard from a score of 60 possibly, or whatever it was, to 55, or whatever it actually is now.
Also, I know of a nearby AFROTC commander from that 2011 time frame that heard of the big impact the new CCT had on being disqualified for pilot training, and took all his pilot candidates to the fairly nearby UPT base to see who would not pass the new CCT, but previously passed the old color dot test things (Ishahara and/or something else). Bad news usually only gets worse with time.
After a brief search on the internet when I was curious about this issue, 1/12 males has the red/green deficiency that is by far the most common color vision issue since the gene is on the piece of the X chromosome males don't have on their Y chromosome. (Mom's fault I guess, sorry). Anyone that has ANY trouble at all with the ishahara dot tests is VERY UNLIKELY to pass even the slightly relaxed version of the Air Force CCT from what I have heard. Navy still DOES NOT use it, and I haven't heard of any intention for them to use it. They still use something called the FLALANT or its newer replacement for color vision screening which fewer candidates fail. Anyone that has their heart set on being a military pilot, and has ANY hint of a color vision deficiency, should do all they can to take the actual Air Force CCT before they commit to the Air Force. GO NAVY!
A search of the internet will come up with a good bit of info on the Air Force CCT and also what the Navy uses. Don't bite off on the color vision correction glasses and contacts that also show up. They are not allowed and easily recognized by the medical folks.
