I do think we need to take into consideration STV is a different company. The rest of the regional licences are ITV owned (to my knowledge).
I don't see why there can't be a regional ident. I though these were actually good (I have used Central as an example) youtu.be 
For me, branding wise, I think ITV could incorporate the UTV logo to look more like an ITV brand.
If ITV ever got control of STV, would expect the same thing.
