Seems they don’t care about the colours and markings, but the MiG and Sukhoi look fairly authentic. Not that can be said for the ‘Orange’ Wilga and ‘silver’ Zlin. Here they are in December 1989, probably when they were still in their original markings.
Those 1989 colours look a lot better than the current colours, as you say they probably don’t lose too much sleep over inauthentic schemes! And thanks for pointing out the broken JPEG, I’ve fixed that up.
