The annax (dot matrix) displays were retained on the 185s and I'd hope they are, I'm yet to see a TOC outside of Thameslink be able to make proper use of them large LCDs.
KeTech ones on East Coast are horrid, they don't actually show the info you need.
Northern are just horrific, there's just no need to have a massive LCD screen and display only static text on it with no sight at all on how they're actually going to make it intelligible.
The 185s have a nice blend of having the Annax DMIs for the critical station information and putting non-critical information on the large LCDs, essentially using them as a poster replacement.
