Hm... Well, I do see - a VERY faded - standard pattern on the "018" and the "122". It is possible they're using non-permanent paint tht washes and/or fades pretty quickly and was just applied to make the equipment look good for the media and the people.
They take what they can get and having evey tank camouflaged is taking time. From what I've seen, the Ukrainians have/use about a DOZEN different patterns for their vehicles - some old, some pretty new and still being tested. There even is some kind of digital pattern seen on some BMD-2s.
The most likely scenario is that older equipment carries old patterns (like the Soviet-era standard 3-tone one), intermediate equipment is rather green than anything else and the newest stuff would be painted in either this digital pattern or the black/grey/green 3-tone one.
