When did the current look for itv2, 3, 4 etc last change? Think only itv 2 has had a change as was red look rest still using original idents launch of the new logo years back?

That would be mostly correct -- ITV2 had a rebrand in 2015, ditching its 2013 look, and CITV replaced its 2013 branding in 2018. ITV3 and ITV4 are both still using their 2013 looks, and ITVBe is still using its launch look from 2014.
